    Identify Z in the sequence \[C{{H}_{3}}COON{{H}_{4}}\xrightarrow{\Delta }X\xrightarrow[\Delta ]{{{P}_{2}}{{O}_{5}}}Y\xrightarrow{{{H}_{2}}O/{{H}^{+}}}Z\]

    A) \[C{{H}_{3}}C{{H}_{2}}CON{{H}_{2}}\]      

    B) \[C{{H}_{3}}CN\]

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

    D) \[{{(C{{H}_{3}}CO)}_{2}}O\]

    Correct Answer: C

    Solution :

    [c] \[C{{H}_{3}}COON{{H}_{4}}\xrightarrow[(-{{H}_{2}}O)]{heat}\underset{X}{\mathop{C{{H}_{3}}CON{{H}_{2}}}}\,\] \[\xrightarrow[(-{{H}_{2}}O)]{{{P}_{2}}{{O}_{5}}}\underset{Y}{\mathop{C{{H}_{3}}CN}}\,\xrightarrow[(-N{{H}_{3}})]{{{H}_{3}}{{O}^{+}}}\underset{Z}{\mathop{C{{H}_{3}}COOH}}\,\]
