    \[C{{H}_{3}}-\underset{\underset{O}{\mathop{||}}\,}{\mathop{C}}\,-C{{H}_{2}}-COO{{C}_{2}}{{H}_{5}}\underset{{{H}_{2}}O}{\mathop{\xrightarrow{NaOH}}}\,A,\]                 product ?A? in the reaction is       [RPMT 2003]

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

    B)                 \[{{C}_{2}}{{H}_{5}}OH\]

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

    D)                 \[{{C}_{2}}{{H}_{5}}CHO\]

    Correct Answer: C

    Solution :

               Ketonic hydrolysis: \[C{{H}_{3}}-CO-C{{H}_{2}}COO{{C}_{2}}{{H}_{5}}\]                                             \[\underset{{{H}_{2}}O}{\mathop{\xrightarrow{NaOH}}}\,C{{H}_{3}}COC{{H}_{3}}+{{C}_{2}}{{H}_{5}}OH+C{{O}_{2}}\]
