    Complete the following reaction : \[C{{H}_{3}}COOH\xrightarrow{?}ClC{{H}_{2}}COOH\xrightarrow{excess\,\,N{{H}_{3}}}?\]

    A) \[{{C}_{2}}{{H}_{5}}OH,\] \[C{{H}_{3}}COON{{H}_{2}}\]

    B) \[HCl,Cl-C{{H}_{2}}COON{{H}_{2}}\]

    C) \[O{{H}^{-}},\text{ }C{{H}_{3}}COON{{H}_{2}}\]

    D) \[P+C{{l}_{2}},\]\[{{H}_{2}}N-C{{H}_{2}}COON{{H}_{4}}\]

    Correct Answer: D

    Solution :

    \[\underset{Acetic\,\,acid}{\mathop{C{{H}_{3}}COOH}}\,\xrightarrow[\begin{smallmatrix}  H.V.Z. \\  reaction \end{smallmatrix}]{P+C{{l}_{2}}}\underset{\begin{smallmatrix}  a-Chloro\, \\  acetic\,\,acid \end{smallmatrix}}{\mathop{ClC{{H}_{2}}COOH}}\,\]\[\xrightarrow[in\,\,excess]{N{{H}_{3}}}{{H}_{2}}N-\underset{Ammonium\,\,glycinate}{\mathop{C{{H}_{2}}COON{{H}_{4}}}}\,\]
