Compound 'A' was prepared by oxidation of compound 'X' with alkaline K

1.	Compound 'A' was prepared by oxidation of compound 'X' with alkaline KMnO_(4). Compound 'A" on reduction with lithium aluminium hydride gets converted back to compound 'B'. When compound C. To which family the compounds 'A', 'B' and 'C' belong to?
Answer» Solution :(i). 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. (II) Since compound 'A' when heated with compound 'B' in presence of `H_(2)SO_(4)`, produces fruity smell of Compound 'C', therefore, 'C' must be an ester, 'A' must be a carboxylic acid and 'B' must be an alcohol. THUS, 'A' is a carboxylic acid, 'B' is an alcohol and 'C' is an ester.
