An aromatic compound (X) (C_(8)H_(8)O) gives positive 2, 4-DNP test. It gives a yellow precipitate of compound (Y) on reaction with iodine and sodium hydroxide solution. (X) does not give Tollens' test on oxidation under drastic conditions. It gives a carboxylic acid (Z) (C_(7)H_(6)O_(2)) .(Z) is also formed with (Y) during the reaction. (X), (Y) and (Z) respectively are
