Nomenclature and Isomerism
Nomenclature implies assigning proper name to a particular compound on the basis of certain standard rules to make their study systematic. The two basic systems employed for naming of the organic compounds are the trivial system and the IUPAC system. IUPAC refers to the International Union of Pure and Applied Chemistry. This system adopts certain uniform rules to write the names of the organic compounds in a systematic manner. The names which are assigned on the basis of these rules are called the IUPAC names. The IUPAC name of an organic compound consists of three parts: root word, prefix and suffix. There are some set rules that are applied for naming of organic compounds. The phenomenon of the existence of two or more compounds having the same molecular formula but different structures is known as isomerism. Organic compounds having the same molecular formula but different structures are known as isomers. Isomerism can be broadly classified into structural isomerism and stereoisomerism. The phenomenon, in which two or more compounds have same molecular formula but they differ from one another in their chemical structures is known as structural isomerism. Different types of structural isomerism are Chain isomerism, Position isomerism, Functional group isomerism and Metamerism.
