A compound 'X' with molecular formula C_2H_4 burns with a sooty flame. It decolourises bromine water. Will it dissolve in water or not ? Will it conduct electricity in an aqueous solution ?

An organic compound (A) with molecular formula C_8H_8 O 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 Tollen's reagent or Fehling's solution , nor does it decolourise bromine water or Baeyer's reagent. On drastic oxidation with chromic acid, it gives a carboxylic acid (B) having molecular formulae C_7H_6O_2 . Identify the compound (A) and (B) and explain the reactions involved .
