Naming organic compounds the increasingly large number of organic compounds identified with each passing day, together with the fact that many of these compounds are isomers of other compounds, requires that a systematic nomenclature system be developed. The full text of iupac and iubmb organic and biochemical nomenclature recommendations international union of pure and applied chemistry recommendations on organic & biochemical nomenclature, symbols & terminology etc. Naming of compounds in organic chemistry is an important aspect in order to identify the specific structure structures can be named in different ways sometimes using by their common names and sometimes by using a nomenclature.
The previous discussion has focused on the carbon framework that characterizes organic compounds, and has provided a set of nomenclature rules that, with some modification, apply to all such compounds. Iupac is the universally-recognized authority on chemical nomenclature and terminology and two iupac bodies take leading roles in this activity: division viii – chemical nomenclature and structure representation and the inter-divisional committee on terminology, nomenclature, and symbols.

Many organic compounds found in nature or created in a laboratory contain rings of carbon atoms with distinguishing chemical properties these compounds are known as cycloalkanes cycloalkanes only contain carbon-hydrogen bonds and carbon-carbon single bonds, but in cycloalkanes, the carbon atoms are joined in a ring.
1 which of the following lists the correct common names for ethanal, methanal, and ethanol, respectively a acetaldehyde, formaldehyde, ethyl alcohol. Iupac nomenclature iupac nomenclature uses the longest continuous chain of carbon atoms to determine the basic root name of the compound the root name is then modified due to the presence of different functional groups which replace hydrogen or carbon atoms in the parent sturcture there are a number of different ways to modify the root name to indicate the functional groups present. This page explains how to write the formula for an organic compound given its name - and vice versa it covers alkanes, cycloalkanes, alkenes, simple compounds containing halogens, alcohols, aldehydes and ketones. Ch 310m/318m organic nomenclature – the basics there are two compounds having the molecular formula c4h10, which differ only in the way the atoms are connected to one another molecules which have the same molecular formula, but different connectivities among the constituent.
Chemistry 121 winter 2001 course notes principles of chemistry ii page 7 organic nomenclature introduction confusion can arise in organic chemistry because of the variety of names that have been applied to compounds common names, trade names and systematic names are prevalent for example, a compound of formula, c6h6o has. In chemical nomenclature, the iupac nomenclature of organic chemistry is a systematic method of naming organic chemical compounds as recommended by the international union of pure and applied chemistry (iupac) it is published in the nomenclature of organic chemistry (informally called the blue book. Nomenclature for chemical compounds additionally contains an explicit or implied relationship to the structure of the compound, in order that the reader or listener can deduce the structure from the name. Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds, which include not only hydrocarbons but also compounds with any number of other elements, including hydrogen (most compounds contain at least one carbon–hydrogen bond), nitrogen, oxygen, halogens, phosphorus, silicon, and sulfur.
