An organic compound (A) with molecular formula C8H8O forms an
orange-red precipitate with 2,4-DNP reagent and gives yellow
precipitate on heating with iodine in the presence of sodium
hydroxide It neither reduces Tollens’ or Fehlings’ reagent, nor does
it decolourise bromine water or Baeyer’s reagent On drastic oxidation
with chromic acid, it gives a carboxylic acid (B) having molecular
formula C7H6O2 Identify the compounds (A) and (B) and explain the
reactions involved
