    \[{{C}_{6}}{{H}_{5}}COCl\xrightarrow{N{{H}_{3}}}X\xrightarrow{{{P}_{2}}{{O}_{5}}}Y\xrightarrow[{{H}_{2}}]{Ni}Z\] The end product in the above sequence of reactions is

    A)  benzole acid       

    B)  aniline

    C)  benzyl amine       

    D)  benzonitrile

    Correct Answer: C

    Solution :

     \[\underset{\text{benzoyl}\,\text{chloride}}{\mathop{{{C}_{6}}{{H}_{5}}COCl}}\,\xrightarrow[-HCl]{N{{H}_{3}}}\underset{\text{Benzamide}}{\mathop{{{C}_{6}}{{H}_{5}}CON{{H}_{2}}}}\,\] \[\xrightarrow[-{{H}_{2}}O]{{{P}_{2}}{{O}_{5}}}\underset{\text{benzonitrile}}{\mathop{{{C}_{6}}{{H}_{5}}CN}}\,\xrightarrow[{{H}_{2}}]{Ni}\underset{\text{benzylamine}}{\mathop{{{C}_{6}}{{H}_{5}}C{{H}_{2}}N{{H}_{2}}}}\,\]
