prefix for 9 in chemistry

Some of the examples show the variations. Prefix Prefixes are added prior to the root of the compounds IUPAC nomenclature. The official provider of online tutoring and homework help to the Department of Defense. Build up names in the same order as in English, for example a 128-sided polygon is called a hecatoicosioctagon. Prefixes in molecular compounds are decided by the number of atoms of each element in the compound. An ionic compound is a chemical compound held together by ionic bonding. See, The numbering adjectives in Greek are inflectional for. *Note: These suffixes, in which the carbon atom is counted as part of the preceding chain, are the most commonly used. Activity\(\PageIndex{2}\): Prefix to Value. IUPAC NOMENCLATURE OF ORGANIC CHEMISTRY- YOUTUBE VIDEO LECTURE RULES. The carbon skeleton is how many carbons are linked to each other. Chemists need to be able to convert between different ways of expressing, but the first step is to memorize the unit definitions themselves. In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended[1][2] by the International Union of Pure and Applied Chemistry (IUPAC). The SECOND element has an -IDE ending. This chronological summary highlights these developments. With one fewer oxygen than the "-ate" ion, the acid will have the suffix "-ous." For example, chlorous acid is HClO 2. CH3F3N+ is trifluoromethylammonium. For example, CH3CH2CH2CH2COOCH3 is methyl pentanoate, and (CH3)2CHCH2CH2COOCH2CH3 is ethyl 4-methylpentanoate. Science KS3 Science - Full Collection KS3 Biology KS3 Chemistry KS3 Physics KS3 Assessment GCSE Science - Full Collection GCSE Biology GCSE Chemistry GCSE Physics GCSE Assessment KS5 Science . The following are not related, but are worth comparing: peri circum around syn/sym, etc. (But this is not necessarily the final grouping, as functional groups may be added in between to ensure all groups are listed alphabetically.). Activity \(\PageIndex{4}\): Abbreviation to Prefix. Each element, carbon and. For example, CH3COOOCCH3 is called ethanoic anhydride and CH3COOOCCH2CH3 is called ethanoic propanoic anhydride. The names of such multiples and submultiples are formed by attaching SI prefix names to the name "gram." You are planning an exercise that will include the m16 and m203. Atom the smallest unit of a chemical element, made from protons, neutrons, and electrons, Prefixes the name that comes before the molecule, Compounds a chemical species composed of two or more elements, Periodic table a table of chemical elements that is arranged in order of atomic number, Oxidation State a number assigned to an element that represents the number of electrons lost or gained, Transition Metal elements from the d-block of the periodic table, which can have more than one configuration of valence electrons, Roman Numerals tells you the oxidation state of the transition metal ion, Element a substance that cannot be chemically broken down into simpler components. The suffix or ending of the name of a hydrocarbon depends on the nature of the chemical bonds between the carbon atoms. What are the 20 prefixes in chemistry? They would be called "6,13-diene", but the presence of alkynes switches it to 6,13-dien. The groups are on carbon atoms 3 and 9. Chart dimensions: 216 mm by 279 mm (8.5 in by 11in). A familiar example is cm, the centimetre symbol. It should have the maximum number of single bonds. The alkyl (R') group is named first. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. (Peta- is word play on penta-, for example. As there are two, we write 3,9-dione. However, many organic cations are obtained by substituting another element or some functional group for a hydrogen. When numbering from right to left, the ketone groups are numbered 15 and 21. The suffixes -diol, -triol, -tetraol, etc., are used for multiple -OH groups: Ethylene glycol CH2OHCH2OH is ethane-1,2-diol. Aldehydes (R-CHO) take the suffix "-al". The aldehyde group is always attached at the end of the main carbon chain, and hence the 1 st position in the . In the latter case, the carbon atoms in the carboxyl groups do not count as being part of the main chain, a rule that also applies to the prefix form "carboxy-". When numbering from left to right, the ketone groups are numbered 3 and 9. Prefix Etymology resources list both soft and hard g pronunciations. E.g. So we would say 16 Gigabytes and not 16,000 Mbytes of 16,000,000 kbytes SI Prefixes SI prefixs are commonly used to represent very large and small numbers. The order of remaining functional groups is only needed for substituted benzene and hence is not mentioned here. If you type 1,200,000 into your calculator and press ENG, it gives 1.2 x 106, so 1,200,000 bytes of memory on a memory stick would be 1.2 MBytes (you do not say 1,200 kBytes). For example, H 2 C=O is named as per the IUPAC system as methanal, commonly known as formaldehyde. understanding and skills required) Key vocabulary. 2 Often, the symbols are used together with units. Other articles where prefix is discussed: steroid: Steroid numbering system and nomenclature: trivial nomenclature, a number of prefixes are often attached, with locants, to the names of steroids to indicate specific modifications of the structure. The ordinal series are based on ordinal numbers such as the English first, second, third (for numbers higher than 2, the ordinal forms are also used for fractions; only the fraction .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}12 has special forms). It basically says, that a pyro compound is one that is formed by heating another compound, usually under the loss of simple molecules like H 2 O or C O 2. Thus, because compound prefixes are unacceptable, symbols for decimal multiples and submultiples of the unit of mass are formed by attaching SI prefix symbols to g (gram). Now, ronna (R) and ronto (r) will describe multiplying factors of 1027 and . Each carbon atom participates in 4 chemical bonds. Number if forward and backward; PREFIXES NUMBER OF CARBON ATOMS WORD ROOT/PREFIX. This is so that the numbers align with SI prefixes and can be read as such. First, you need to determine what type of compound it is. Bibliography of IUPAC Recommendations on Organic Nomenclature, "Improving the Quality of Published Chemical Names with Nomenclature Software", American Chemical Society, Committee on Nomenclature, Terminology & Symbols, https://en.wikipedia.org/w/index.php?title=IUPAC_nomenclature_of_organic_chemistry&oldid=1138073631, Articles needing additional references from April 2019, All articles needing additional references, Articles with unsourced statements from January 2012, Wikipedia articles needing clarification from February 2016, Creative Commons Attribution-ShareAlike License 3.0, It should have the maximum number of substituents of the suffix functional group. where each "#" represents a number. If a higher precedence suffix is in use, the prefix "oxo-" is used: CH3CH2CH2COCH2CHO is 3-oxohexanal. Activity\(\PageIndex{3}\): Value to Prefix. Also, the vowel at the end of a prefix is sometimes dropped when the name of the element begins with a vowel. The purpose of organic chemistry nomenclature is to indicate how many carbon atoms are in a chain, how the atoms are bonded together, and the identity and location of any functional groups in the molecule. In chemistry, tetra- is specifically used to indicate four atoms or four groups of atoms in compounds, e.g., tetrachloride. Some words comprising numerical prefixes are hybrid words. Just sayin'. 4) Prefix the root word with the infix "cyclo" if the parent chain is cyclic; or with the infix "spiro" if it is a spiro compound; or with the infix "bicyclo" if the compound is bicyclic. Section 7 1 Naming and Writing Formulas for Molecular Compounds The prefix in the name of a binary molecular compound tells how many atoms of each element are present in each molecule of the compound to The common name for an aldehyde is derived from the common name of the corresponding carboxylic acid by dropping the word acid and changing the suffix from -ic or -oic to -aldehyde. The table is arranged in a symmetric fashion for convenience of comparison. Here is the list for some commonly used prefixes10 12 Pico10 9 Nano10 6 Micro10 3 Milli10 2 Centi10 1 Deci10 3 Kilo10 6 Mega10 9 Giga10 12 Tera. Introduction to Chemistry Prefixes Number of Atoms: Prefixes 1: mono 2: di 3: tri 4: tetra 5: penta 6: hexa 7: hepta 8: octa 9: nona 10: deca The above list shows the 10 most basic chemistry prefixes for naming compounds, which come from Greek. Covalent compounds have Greek numerical prefixes to indicate the number of atoms. A teacher walks into the Classroom and says If only Yesterday was Tomorrow Today would have been a Saturday Which Day did the Teacher make this Statement? 1. In order to correctly convert one metric unit to another, you will need to determine which of two prefixes represents a bigger amount and then determine the exponential "distance" between them. Metric or SI (Le Systme International d'Units) prefix are based on powers of ten.They are modifiers on the root word that tell us the unit of measure. Side chains are the carbon chains that are not in the parent chain, but are branched off from it. Cyclic alkanes are simply prefixed with "cyclo-": for example, C4H8 is cyclobutane (not to be confused with butene) and C6H12 is cyclohexane (not to be confused with hexene). NOTE: If you already know an answer you can just click "I got it right" and move on to the next. If the oxygen is not attached to the end of the main alkane chain, then the whole shorter alkyl-plus-ether group is treated as a side-chain and prefixed with its bonding position on the main chain. Legal. 2 4. Therefore, HClO 4 is called perchloric acid. The CGPM decided to expand the list of SI prefixes to encompass a larger range of numbersboth massive and minuscule. SI Prefix symbols are featured in the chart and used to represent smaller or larger units by factors that are powers of 10. It will be called 19-yne. Three for forming submultiples: micro, nano, and pico. Some of the examples show the variations. The di-, tri- etc. The name of each substitution is prefixed to the hydride cation name. If there are multiple functional groups of the same type, either prefixed or suffixed, the position numbers are ordered numerically (thus ethane-1,2-diol, not ethane-2,1-diol.) Share sensitive information only on official, secure websites. (mega- is not derived from a number word, for example.) This makes it a prime target for teachers to test. Helmenstine, Anne Marie, Ph.D. "Organic Chemistry Prefixes and Suffixes." The IUPAC nomenclature scheme becomes rapidly more elaborate for more complex cyclic structures, with notation for compounds containing conjoined rings, and many common names such as phenol being accepted as base names for compounds derived from them. "cyclohexyl-") or for benzene, "phenyl-". The result is you can express any number with between 1 and 999 values to the left of the decimal, followed by the appropriate SI prefix. Number of Carbon 1 2. So a memory stick with 1,200,000 bytes would be written as 1.2 Mbyte, not as 1,200 kbytes. In certain cases, particularly in scientific usage, it becomes convenient to provide for multiples larger than 1000 and for subdivisions smaller than one-thousandth. Why were Mexican workers able to find jobs in the Southwest? Was this answer helpful? If both acyl groups are the same, then the name of the carboxylic acid with the word acid is replaced with the word anhydride and the IUPAC name consists of two words. . For example, a chain of six carbon atoms would be named using the prefix hex-. For example, CH3OCH2CH3 could also be called 2-oxabutane, and an epoxide could be called oxacyclopropane. Simple cations formed by adding a hydron to a hydride of a halogen, chalcogen or pnictogen are named by adding the suffix "-onium" to the element's root: H4N+ is ammonium, H3O+ is oxonium, and H2F+ is fluoronium. Introduction to Paragraphs PowerPoint. Its order of magnitude is -2 against the metre, and its representation is 0.01. chlorofluoromethane, not fluorochloromethane. According to the current version of Nomenclature of Organic Chemistry - IUPAC Recommendations and Preferred Names 2013 (Blue Book), simple prefixes (simple substituent groups consisting of just one part that describes an atom, or group of atoms as a unit, for example methyl, cyclohexyl, and isopropyl) are arranged alphabetically disregarding any Hydrocarbons with halogen substituents are named using prefixes, such as fluoro-, chloro-, bromo-, iodo-, and the general halo- when the element identity isn't specified. To make life easier, you dont need to include the prefix mono for the first element of the two. * SI base or derived units with special names may be used. Prefix Symbol Meaning ; deci: d: 10-1 centi: c 10-2 milli: m 10-3 micro: Prefixed substituents are ordered alphabetically (excluding any modifiers such as di-, tri-, etc. See its etymology for details.). Each alkane name is built from a prefix (first part) and a suffix (ending). 107. Prefixes, symbols, orders, and names for large . \[ \begin{align} 1,330,000,000m& =1.33\times 10^{9}m =1.33 \; gigameters\nonumber \\13,300,000,000m& =13.3 \times 10^{9}m=13.3 \;gigameters\nonumber\\ 133,000,000,000m& =133\times 10^{9}m = \; 133 \; gigameters\end{align}\]. Department of Chemistry and Biochemistry Fayetteville, Arkansas 72701. With a little bit of practice, naming compounds will become easier and easier! Identification of the side-chains. We have all heard of SI prefixes, for example you may have a 16 Gbyte flash drive, where the G stands for giga and means 109, and that is a much more convienent way of expressing the number of bytes than using the floating number of 16,000,000,000 bytes. NOTE: If you already know an answer you can just click "I got it right" and move on to the next. Several technical numerical prefixes are not derived from words for numbers. If many substitutions by the same functional group occur, then the number is indicated by prefixing with "di-", "tri-" as with halogenation. Alcohols (R-OH) take the suffix "-ol" with an infix numerical bonding position: CH3CH2CH2OH is propan-1-ol. The rest are named with a Greek numeric prefix, with the exceptions of nonane which has a Latin prefix, and undecane which has mixed-language prefixes. I cover the defin. Simple cis and trans isomers may be indicated with a prefixed cis- or trans-: cis-but-2-ene, trans-but-2-ene. For example, C(CH3)4 (neopentane) is named 2,2-dimethylpropane. Some examples of ionic compounds are sodium chloride (NaCl) and sodium hydroxide (NaOH). Here is a sample molecule with the parent carbons numbered: For simplicity, here is an image of the same molecule, where the hydrogens in the parent chain are removed and the carbons are shown by their numbers: The final name is (6E,13E)-18-bromo-12-butyl-11-chloro-4,8-diethyl-5-hydroxy-15-methoxytricosa-6,13-dien-19-yne-3,9-dione. This pack includes 36 Prefix and Suffix task cards that would fit into any class activity, or as a center/station in your Literacy Block.Included:- Task Cards- Recording Sheets- Answer Keys and Suggestions- 2 Signs/PostersSimply print (back if you want), laminate, cut and organize to use in your cla. Thus, one kilobit, or 1 kbit, is 1000 bit and not 2 10 bit = 1024 bit. Learn how to easily name ionic and covalent compounds. The first three of the names shown above are still considered to be acceptable IUPAC names. Numeric prefixes (mono, di, tri, tetra, penta, hexa, hepta, octa, nona, deca) These are ONLY used for the following: -Metal-containing acids and acid ions: the prefix ONLY goes on the hydrogen (mono is dropped) . { "2.01:_Mathematical_Fundamentals" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.02:_Algebra_Review" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.03:_Numbers" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.04:_Units_of_Measurement" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.05:_Measured_Numbers_and_Significant_Digits" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.06:_Scientific_Notation" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.07:_SI_Prefixes" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.08:_Unit_Conversions_and_Dimensional_Analysis" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.09:_Fractions_and_Percent" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "2.10:_Graphing_and_Temperature_Conversions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "00:_General_Information" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "01:_Introduction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "02:_Mathematical_Fundamentals" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "03:_Atoms_and_Elements" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "04:_Compounds_and_Molecules" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "05:_Chemical_Reactions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "06:_Counting_Molecules_through_Measurements" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "07:_Stoichiometry" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "08:_Solution_Chemistry" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "09:_Gases" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "10:_Thermodynamics" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "authorname:belfordr" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FCourses%2FUniversity_of_Arkansas_Little_Rock%2FChem_1300%253A_Preparatory_Chemistry%2FLearning_Modules%2F02%253A_Mathematical_Fundamentals%2F2.07%253A_SI_Prefixes, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), 2.8: Unit Conversions and Dimensional Analysis, status page at https://status.libretexts.org, Elena Lisitsyna& Vincent Belford(H5P interactive modules). The common prefixes are given in this Table. The anesthetic halothane (CF3CHBrCl) is 2-bromo-2-chloro-1,1,1-trifluoroethane. For example, NO2 would be called nitrogen dioxide, not mononitrogen dioxide. These prefixes can be used to name just about any compound. Here's the thing, each of these prefixes have their own abbreviation/symbol. Several common-use numerical prefixes denote vulgar fractions. Scientific notation is a useful means to write out very large or very small numbers using powers of ten and exponents. This is done by first numbering the chain in both directions (left to right and right to left), and then choosing the numbering which follows these rules, in order of precedence. Again, the substituent groups are ordered alphabetically. The naming system is used by determining the number of each atom in the compound. There is chemistry all around us every day, even if we dont see it. Official websites use .gov It is important that you do this as you will not be able to follow the science later on in the course if you do not understand the meanings of the terms used. 2 The smaller number is always used, not the sum of the constituents numbers. Every hydrogen is joined to a carbon. You also need to know them to figure out the formula from their names. Lock NIST SI Measurement System Chart (2021) is a colorful chart explaining the 7 base units of the SI, prefix symbols, and features the Measurement League: Guardians of the SI. For example: In many European languages there are two principal systems, taken from Latin and Greek, each with several subsystems; in addition, Sanskrit occupies a marginal position. Also, very long names may be less clear than structural formulas. Dont worry about those rules for now its just something to keep in the back of your mind! However, these compounds have many positively and negatively charged particles. End the name of the second element with the suffix -ide. with Be sure not to confuse: anti (Greek "against") and ante (Latin "before") a/an (Greek "not") and ab/a/ abs (Latin "away from") dys (Greek "bad, disordered") and dis (Latin "apart, in different directions, not") In almost every case, Latin prefixes are used with Latin bases and Greek . H5C+ is methanium, HO-(O+)-H2 is dioxidanium (HO-OH is dioxidane), and H2N-(N+)-H3 is diazanium (H2N-NH2 is diazane). . The ENG key takes large or small numbers and expresses them as integer multiples of 103 or 10-3, effectively converting them to values that can be expressed with SI prefixes. You will also learn the basics of these chemistry prefixes and how they are applicable in the real world today! There are other important organic suffixes: This table lists the organic chemistry prefixes up to 20 carbons in a simple hydrocarbon chain. Symbols as prefixes exist for large and small values, and every prefix and symbol represents an order of magnitude. Eight original SI prefixes were officially adopted: deca, hecto, kilo, myria, deci, centi, milli, and myrio, derived from Greek and Latin numbers. There is one triple bond between carbon atoms 19 and 20. This created an imbalanced situation, where there were, Manufacturing Extension Partnership (MEP), Resources for Continuing Education and Training, Quick Guide for OWM Contacts System (PDF), How to Request Publications using OWM Contacts System (PDF), How to Request Training & Transcript Using the Contacts System (PDF), How to Reset Password Using the Contacts System (PDF), The National Conference on Weights and Measures (NCWM), Commonly Used Metric System Units, Symbols, and Prefixes. The breadth, depth and veracity of this work is the responsibility of Robert E. Belford, rebelford@ualr.edu. The same suffix may be used with more than one series: Because of the common inheritance of Greek and Latin roots across the Romance languages, the import of much of that derived vocabulary into non-Romance languages (such as into English via Norman French), and the borrowing of 19th and 20th century coinages into many languages, the same numerical prefixes occur in many languages. As there are two, we write 3,9-dione. Note, on the flash cards you can skip a card by clicking. Rachel Lynette. Alternatively, the suffix "-carboxylic acid" can be used, combined with a multiplying prefix if necessary mellitic acid is benzenehexacarboxylic acid, for example. The cardinal series are derived from cardinal numbers, such as the English one, two, three. (CH3)3O+ is trimethyloxonium. You will need the prefixes in order to give a proper name of many compounds. to include a prefix that indicates the number of hydroxyl groups present (-anediol, -anetriol, etc.).
