    \[{{C}_{6}}{{H}_{5}}N{{O}_{2}}\xrightarrow[{}]{Zn+NaOH}\] Product The product of reaction is

    A)  \[{{C}_{6}}{{H}_{5}}-NH-NH-{{C}_{6}}{{H}_{5}}\]

    B)  \[{{C}_{6}}{{H}_{5}}-N=N-{{C}_{6}}{{H}_{5}}\]

    C)  \[{{C}_{6}}{{H}_{5}}-\underset{\downarrow }{\mathop{N}}\,={{C}_{6}}{{H}_{5}}\]

    D)  \[{{C}_{6}}{{H}_{5}}N{{H}_{2}}\]

    Correct Answer: A

    Solution :

     \[\underset{chloropicrin}{\mathop{2{{C}_{6}}{{H}_{5}}N{{O}_{2}}}}\,+10[H]\xrightarrow[alco.KOH]{zn+NaOH}\] \[\underset{nitrobenzene}{\mathop{{{C}_{6}}{{H}_{5}}-NH-NH-{{C}_{6}}{{H}_{5}}}}\,+4{{H}_{2}}O\]
