	IUPAC nomenclature of organic chemistry - Wikipedia, the free encyclopedia
		The IUPAC nomenclature of organic chemistry is a systematic way of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC).
		In IUPAC nomenclature, a number of prefixes, suffixes and infixes are used to describe the type and position of functional groups in the compound.
		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, furan, indole, etc. being accepted as base names for compounds derived from them.

	IUPAC nomenclature - Wikipedia, the free encyclopedia
		IUPAC nomenclature is a system of naming chemical compounds and of describing the science of chemistry in general.
		The primary function of chemical nomenclature is to ensure that the person who hears or reads a chemical name is under no ambiguity as to which chemical compound it refers: each name should refer to a single substance.
		While IUPAC has a human-readable advantage over CAS numbering, it would be difficult to claim that the IUPAC name for some larger, relevant molecules (such as rapamycin) are human-readable, and so most researchers simply use the informal names.

		There is also a IUPAC system for naming inorganic compounds, see the systematic name page for details.
		For common ketones some traditional names such as acetone and benzophenone predominate, and these are acceptable IUPAC names (http://www.acdlabs.com/iupac/nomenclature/93/r93_701.htm), although some introductory chemistry texts use alternative names for acetone such as propan-2-one or propanone (see diagram).

	International Union of Pure and Applied Chemistry - Wikipedia, the free encyclopedia
		The International Union of Pure and Applied Chemistry (IUPAC) is an international non-governmental organization devoted to the advancement of chemistry.
		It is most well known as the recognized authority in developing standards for the naming of the chemical elements and their compounds, through its Interdivisional Committee on Nomenclature and Symbols (IUPAC nomenclature).
		In addition to nomenclature guidelines, the IUPAC sets standards for international spelling in the event of a dispute; for example, it ruled that aluminium is preferable to the American aluminum and sulfur rather than the British sulphur.

		IUPAC Chemical Identifier Project http://www.iupac.org/nomenclature/chem_id_project.html The aim of the Chemical Identifier project is to establish a unique label, the IUPAC Chemical Identifier (IChI), which would be a non- proprietary identifier for chemical substances that could be used in printed and electronic data sources thus enabling easier linking of diverse data and information compilations.
		JT Dunnen, SE Antonarakis SE "Mutation nomenclature extensions and suggestions to describe complex mutations: a discussion" Human Mutation 2000; 15 (1): 7- 12 While a codified mutation nomenclature system for simple DNA lesions has now been adopted broadly by the medical genetics community, it is inherently difficult to represent complex mutations in a unified manner.
		Nomenclature committees were soon established for both the human and mouse genes and guidelines (White et al., 19972 and Maltais LJ et al., 19973) published in conjunction with the reports from the HGM (Human Genome Mapping) meetings.

		The nomenclature of organic chemistry is both a tool and a symbol of the chemist's mastery over molecules of modest size.
		The complexity of very large organic molecules, and practically all large biochemical molecules, prevents their nomenclature from becoming usefully systematic and encourages the use of nicknames, leaving communication of structural detail to pictures.
		This "Geneva Nomenclature" contained the core of the system that, as IUPAC nomenclature (International Union of Pure and Applied Chemistry), remains in use after more than 100 years and is constantly being updated to deal with the latest challenges in structural chemistry.

		So far, the IUPAC is content to modify basic usages instituted in the 1800’s, rather than move to a totally different system.
		Similar to modern languages, organic nomenclature has a variety of usages, many of which are akin to slang in spoken languages.
		The IUPAC disapproves of having vowels together, so the “e” of “butane” is dropped.

		In certain areas, and particularly in metrology, it is important for IUPAC to retain consistency with definitions given by ‘higher authorities’ such as in the International Vocabulary of Basic and General Terms in Metrology [VIM; ref.
		Nomenclature in all areas of chemistry is continuously under development within IUPAC, and the pages of Pure and Applied Chemistry should be consulted for recent Recommendations.
		In the preparation of nomenclature documents it is also helpful, as for definitions, if individual rules are given in numbered paragraphs together with explanatory notes and examples, as required.

		The IUPAC rules for naming compounds are extremely long, as they have to deal with everything from the correct name for table salt (sodium chloride), to the systematic name for cotton boll worm pheromones ((7E, 11Z)-hexadeca-7,11-dienyl ethanoate).
		IUPAC nomenclature is supposed to do away with such redundancy so that a chemical has one correct name, and no other.
		IUPAC naming has gone some ways to making the world of the inorganic chemist simpler, and has made some headroads into the world of the organic chemist.

		The first 'system' of chemical nomenclature was developed by Guyton de Morveau in 1782.[1] Guyton's statement of the need for a 'constant method of denomination, which helps the intelligence and relieves the memory' is still true today.
		The first comprehensive report of the IUPAC inorganic commission, in 1940,[7] had a major effect on the systematization of inorganic nomenclature and made many chemists aware of the necessity for developing a more fully systematic nomenclature.
		Nomenclature is important in Coordination Chemistry because of the need to have an unambiguous method of describing formulae and writing systematic names, particularly when dealing with isomers.

		To reiterate that polymer scientists and technologists need nomenclature is perhaps redundant, but the fundamental reason is so important that it bears repeating: standardized or universally understood nomenclature is needed, not only to improve communication among the scientific community, but also to connect the known (or perhaps idealized) structure of a polymer with its name.
		Along with the need for nomenclature for these new types of polymers, of course, came a need for broader terminology in polymer science — that is, terms relating to processes, reactions, and properties.
		Because no formal nomenclature systems exist for some new families of polymers, some pioneers have devised and published their own;1g,2,3c,4 this is laudable, although the resulting systems may not be universally applicable.

		Nomenclature in organic chemistry is of two types: common (or trivial) and systematic.
		Bicyclic compounds are named in the IUPAC system by counting the number of carbons in the ring system, assigning to the structure the base name of the unbranched alkane having the same number of carbon atoms, and attaching the prefix bicyclo-.
		Substitutive nomenclature of alkyl halides treats the halogen as a halo- (fluro-, chloro-, bromo-, or iodo-) substituent on an alkane chain.

		The basic premises of the systematic IUPAC nomenclature of ternary compounds are similar to the ones for binary compounds.
		The IUPAC method for naming ternary compounds is to take a binary-type name using two elements, alter the ending to -ate to designate it as a non-binary compound, and then specify the number and type of added atoms as a prefix to the name or names of the element(s) to which they are attached.
		It differs from the IUPAC method in that the number of oxygens is not given directly (no oxo substituents), and oxidation states are not given.

	Nomenclature: Selected Aspects
		This page covers the trivial and the systematic (IUPAC) nomenclature of the alkanes and alkyl groups having five carbons or less, as well as the alkyl halides and alcohols derived by attaching halogen substituents to those alkyl groups.
		In trivial nomenclature, alkanes with a single methyl branch on the second-to-last carbon are named as the "iso-" version of that formula.
		Notice the similarity of these names to the corresponding trivial and systematic names of the alkane--"isobutane" and "2-methylpropane" (structure shown to the left)--from which the chlorine-containing compound was derived.
