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

The available data suggests that compound 'A' is an acid. The compound 'B' is an alcohol and it gives the acid 'A' upon oxidation with alkaline `KMnO_(4)`. Similarly when the acid 'A' is reduced with `LiAlH_(4)`, alcohol 'B' is formed. The two compounds i.e., 'A' and 'B' react in the presence of `H_(2)SO_(4)` to form an ester 'C'. The reaction is called esterification reaction. For details of the reactions, consult section 18.
