Nomenclature, Werner’s theory

Organic Compound Nomenclature A systematic name for an organic compound is formed by first selecting and then identifying a parent structure. This basic name is then supplemented by prefixes, infixes, and, in the case of a parent hydride, suffixes that indicate the structural modifications required to form the compound in question from the parent structure.

What is IUPAC Nomenclature? The IUPAC nomenclature of organic compounds refers to a systematic nomenclature of organic compounds as recommended by the International Union of Pure and Applied Chemistry (often abbreviated to IUPAC). It became necessary to adopt a systematic approach to organic compound nomenclature because of the sheer volume of new organic compounds discovered.

IUPAC stands for International Union of Pure and Applied Chemistry. It was supported in 1919 as a replacement for the International Congress of Applied Chemistry. The headquarters of this organisation is found within the USA.  IUPAC is the international organisation for standardisation atomic weights, symbols, language, etc. of assorted chemicals. It develops and maintains such
