    \[{{C}_{6}}{{H}_{5}}N{{O}_{2}}\xrightarrow{Sn/HCl}{{C}_{6}}{{H}_{5}}X\]X is identified as:

    A)  NO                                       

    B)  \[N{{H}_{2}}\]

    C)  NHOH                                 

    D)  none of these

    Correct Answer: B

    Solution :

                     \[\underset{\text{Nitrobenzene}}{\mathop{{{C}_{6}}{{H}_{5}}N{{O}_{2}}}}\,\xrightarrow[[H]]{Sn/HCl}\underset{\text{Aniline}}{\mathop{{{C}_{6}}{{H}_{5}}N{{H}_{2}}}}\,\] Nitrobenzene on reduction with Sn and HCl produce aniline. Hence, X is identified as \[N{{H}_{2}}\]group.
