    Which of the following has the most acidic proton [Roorkee Qualifying 1998]

    A)                 \[C{{H}_{3}}COC{{H}_{3}}\]        

    B)                 \[{{(C{{H}_{3}})}_{2}}C=C{{H}_{2}}\]

    C)                 \[C{{H}_{3}}COC{{H}_{2}}COC{{H}_{3}}\]              

    D)                 \[{{(C{{H}_{3}}CO)}_{3}}CH\]

    Correct Answer: D

    Solution :

                    \[\begin{matrix}    C{{H}_{3}}CO  \\    {}  \\    C{{H}_{3}}CO  \\ \end{matrix}\underset{\,\,\,\,\,\,\,OCC{{H}_{3}}}{\mathop{_{\swarrow }^{\nwarrow }\underset{{}}{\mathop{\underset{\downarrow }{\mathop{C}}\,\,--\,H}}\,}}\,\] So most acidic in nature.
