![]() ![]() The rules discussed are based on guide books published by IUPAC in 1979 (Nomenclature of Organic Chemistry by J Rigandy and S.P. The most comprehensive rules for nomenclature of organic compounds and names were first published in 1979 and later revised, modified and updated in 1993. ![]() Thus this system of nomenclature of organic compound was first introduced in 1947 and was changed from time to time. The new system is called IUPAC system of naming the compound. They adopted certain uniform rules for naming or nomenclature of the organic compounds/ naming organic compound: The system of nomenclature was named as the Geneva system and since then the system of naming has been modified by the International Union of Pure and Applied Chemistry which is full form of IUPAC in chemistry. In an attempt to rationalise the system of naming an International Congress of Chemists was held in Geneva in 1892. Nomenclature meaning in Tamil is Peyargal IUPAC system of nomenclature of carbon compounds Such a type of a system of nomenclature is known as a trivial system. These names are without any systematic basis or rules and are known as common names or trivial matters. Similarly, methyl alcohol was known as wood spirit since it could be obtained as one of the products during the destructive distillation of wood and formic acid derived its name from the Greek word formicus (red ants) since the acid could be obtained from red ants’ species. In previous days, the organic compounds were named after the source from which they were obtained, as in example, urea got its name because the compound was obtained from the urine of the mammals.
