An aromatic compound 'X' with molecular formula C_(9)H_(10)O gives the following chemical tests: (i) forms 2,4-DNP derivative. (ii) Reduces tollens' reagent. (iii) undergoes Cannizzaro reaction and (iv) on vigorous oxidation, 1,2-benzene-dicarboxylic acid is obtained.

Answer»




SOLUTION :Since compound 'X' FORMS a 2,4-DNP, it must be an ALDEHYDE or a ketone. Since it REDUCES tollens' reagent, it must be an aldehyde. Since on oxidation, it gives 1,2-benzenedicarboxyolic acid, it must be an o-alkyl substituted benzaldehyde. Thus, the compound is o-ethylbenzaldehyde, i.e., option (a) is CORRECT.
