An organic compound (X) with molecular formula `C_8H_8O` forms an orange red precipitate with 2, 4 - DNP regent and resonds iodoform test. It neither decolourises Baeyer's reagent or bromine water and also it neither reduces Tollen's reagent or Fehling's reagent. Compound (X) gives a carboxylic acid (Y) with molecular formula `C_7H_6O_2` on drastic oxidation with chromic acid . Give the equations.
