    B)        Isopropyi alcohol

    C) Acetone

    D)        Ethanol

    Correct Answer: C

    Solution :

    [c] \[HC\equiv CH\xrightarrow[20%{{H}_{2}}S{{O}_{4}}]{1%HgS{{O}_{4}}}\underset{[A]}{\mathop{C{{H}_{3}}CHO}}\,\xrightarrow[{{H}_{2}}O]{C{{H}_{3}}MgX}\] \[\underset{[B]}{\mathop{C{{H}_{3}}CHOHC{{H}_{3}}}}\,\xrightarrow{[O]}\underset{\text{Acetone}\,\text{ }\!\![\!\!\text{ C }\!\!]\!\!\text{ }}{\mathop{C{{H}_{3}}COC{{H}_{3}}}}\,\]
