An organic compound (X) with molecular formula C3H6O is not readily oxidised. On reduction it gives C3H8O (Y) which reacts with HBr to give a bromide (Z) which is converted to Grignard’s reagent. Grignard’s reagent reacts with (X) to give 2, 3-dimethylbutan-2-ol. (X), (Y) and (Z) respectively are

  1. CH3COCH3, CH3CH2CH2OH, CH3CH(Br)CH3
  2. CH3CH2CHO, CH3CH CH2, CH3CH(Br)CH3
  3. CH3COCH3, CH3CH(OH)CH3, CH3CH(Br)CH3
  4. CH3CH2CHO, CH3CH2CH2OH, CH3CH2CH2Br

Answer

(C) CH 3 COCH 3 , CH 3 CH(OH)CH 3 , CH 3 CH(Br)CH 3
