Document Summary

Write a brief account of nomenclature of aldehydes. In the trivial or common system, aldehydes are named after the carboxylic acids they form an oxidation. The name is obtained by replacing the terminal ic acid" in the name of the acid by the suffix aldehyde. Ch3 cho (or) ch3 c = o. In the iupac system, the ending of the name (suffix) of aldehyde is al". The names of aliphatic aldehydes are derived from the name of the corresponding alkane by replacing the terminal e" by the suffix al". i. e. , name of aldehyde = name of corresponding alkane e + al. In the above example, one carbon atom is present i. e. , the parent hydrocarbon is methane. Methanal: ch3 cho ( 2- carbon atoms present) Ethanal: ch3 ch2 cho (propanal) The common and iupac names of some aldehydes are given below. Butanal: write a brief account of nomenclature of ketones.
