    In the reaction\[C{{H}_{3}}C{{H}_{2}}COON{{H}_{4}}\xrightarrow{{{P}_{2}}{{O}_{2}}}A\xrightarrow{{\scriptstyle{}^{{{H}^{+}}}/{}_{{{H}_{2}}O}}}B\]A and B are

    A)  \[C{{H}_{3}}C{{H}_{2}}CON{{H}_{2}},C{{H}_{3}}C{{H}_{2}}CO{{O}^{-}}\]

    B)  \[C{{H}_{3}}C{{H}_{2}}COON{{H}_{2}},C{{H}_{3}}C{{H}_{2}}COOH\]

    C)  \[C{{H}_{3}}C{{H}_{2}}CN,C{{H}_{3}}C{{H}_{2}}COOH\]

    D)  \[C{{H}_{3}}C{{H}_{2}}CN,C{{H}_{3}}C{{H}_{2}}CO{{O}^{-}}\]

    Correct Answer: C

    Solution :

    \[C{{H}_{3}}C{{H}_{2}}COON{{H}_{4}}\xrightarrow[-2{{H}_{2}}O]{{{P}_{2}}{{O}_{5}}}C{{H}_{3}}C{{H}_{2}}CN\xrightarrow{{}^{{{H}^{+}}}/{}_{{{H}_{2}}O}}\]                                                 \[\underset{\text{Propanoic acid}}{\mathop{C{{H}_{3}}C{{H}_{2}}COOH}}\,\]
