    A) \[{{C}_{2}}{{H}_{5}}OH\]     

    B) \[C{{H}_{3}}CHO\]

    C) \[C{{H}_{3}}COC{{H}_{3}}\] 

    D) \[C{{H}_{3}}COOH\]

    Correct Answer: A

    Solution :

    [a] : \[\underset{'X'}{\mathop{C{{H}_{3}}}}\,C{{H}_{2}}OH\xrightarrow[C{{H}_{2}}C{{l}_{2}}]{PCC}\underset{'Y'}{\mathop{C{{H}_{3}}}}\,CHO\] \[\xrightarrow[{}]{{{1}_{2}}/NaOH}CH{{I}_{3}}\downarrow \]
