    The enol form of acetone after treatment with \[{{D}_{2}}O\] gives:

    A) \[C{{H}_{3}}-\overset{OD}{\mathop{\overset{|}{\mathop{C}}\,}}\,=C{{H}_{2}}\]       

    B) \[C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,=C{{D}_{3}}\]

    C) \[C{{H}_{2}}=\overset{OH}{\mathop{\overset{|}{\mathop{C}}\,}}\,-C{{H}_{2}}D\]

    D)   \[C{{D}_{2}}=\overset{OD}{\mathop{\overset{|}{\mathop{C}}\,}}\,-C{{D}_{3}}\]

    Correct Answer: A

    Solution :

    [a] The enol form of acetone is \[C{{H}_{3}}-\overset{OH}{\mathop{\overset{|}{\mathop{C}}\,}}\,=C{{H}_{2}}\] with \[{{D}_{2}}O\] it gives \[C{{H}_{3}}-\overset{OD}{\mathop{\overset{|}{\mathop{C}}\,}}\,=C{{H}_{2}}\]
