    End product of the following reaction is: \[C{{H}_{4}}C{{H}_{2}}COOH\xrightarrow[redP]{C{{l}_{2}}}\xrightarrow{alcoholic\,KOH}\]

    A)  \[C{{H}_{3}}\underset{OH}{\mathop{\underset{|}{\mathop{CHCOOH}}\,}}\,\]  

    B)  \[C{{H}_{2}}\underset{OH}{\mathop{\underset{|}{\mathop{C{{H}_{2}}COOH}}\,}}\,\]

    C)  \[C{{H}_{2}}=CHOOH\]

    D)  \[\underset{OH}{\mathop{\underset{|}{\mathop{C{{H}_{2}}}}\,}}\,\underset{OH}{\mathop{\underset{|}{\mathop{CHCOOH}}\,}}\,\]

    Correct Answer: C

    Solution :

       \[C{{H}_{3}}C{{H}_{2}}COOH\xrightarrow[P]{C{{l}_{2}}}C{{H}_{3}}\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\mathop{CH}}\,-COOH\]             \[\xrightarrow{KOH(alc.)}\,C{{H}_{2}}\,=CHCOOH\]
