IUPAC nomenclature for organic compounds considers these radicals as side chains which are indicated by their location on the parent chain. The compound is considered to have been derived from the parent structure by the replacement of hydrogens by various alkyl groups. The systematic approach taken for the nomenclature of organic compounds as per the recommendation of the International Union of Pure and Applied Chemistry (often abbreviated to IUPAC) is known as IUPAC nomenclature of organic compounds. Saturated acyclic hydrocarbons are … The chain is then numbered from one end to the other, the end chosen as number 1 is that which gives the smaller number at the first point of difference . •Official IUPAC naming recommendations are not always followed in practice, and the common or trivial name may be used. Earlier, a common system of nomenclature was used, but later on, when naming with common system became tedious, the scientists thought of making a logical and more scientific approach. IUPAC rules that have been developed for naming then are summarized below: 1. Name this chain as if it were a straight chain alkane. These rules may be called the IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry. IUPAC Nomenclature of cyclic compounds. 1. •It provides an unambiguous structure.
