Compound 'A' was prepared by oxidation of oxidation of compound 'B' with alkaline `KMnO_(4)` Compound 'A' on reduction with lithium aluminium hydride gets converted B in the presence of `H_(2)SO_(4)` it produces fruity smell of compound C to which family the compounds 'A', 'B' and 'C' belong to ?

Explanation

1. Since compound .A. is obtained by oxidation of compound .B. and reduction of compound .B. with `LiAlH_4` gives back compound .A., therefore, both compounds .A. and .B. have the same number of carbon atoms. 2. Since compund .A. when heated with compound .B. in presence of H2SO4, produces fruity smell of compound .C.. therefore, .C. must be an ester formed by the reaction between an alcohol and a carboxylic acid. Reactions involved are:

Thus, .A. is carboxylic acid, .B. is an alcohol and c. is an ester.
