    \[CHC{{l}_{3}}+{{C}_{6}}{{H}_{5}}N{{H}_{2}}+3NaOH\xrightarrow{{}}A\] \[+\,3B\,+3C\] In the above reaction, the product A is

    A)  chlorobenzene               

    B)  phenyl isocyanide

    C)         phenyl cyanide

    D)         phenyl chloride

    Correct Answer: B

    Solution :

    \[CHC{{l}_{3}}+{{C}_{6}}{{H}_{5}}N{{H}_{2}}+3NaOH\xrightarrow{{}}\] \[\underset{\text{Phenyl}\,\text{isocyanide}}{\mathop{\underset{(A)}{\mathop{{{C}_{6}}{{H}_{5}}NC}}\,}}\,+\underset{(B)}{\mathop{3NaCl}}\,+\underset{(C)}{\mathop{3{{H}_{2}}O}}\,\] Hence, product A is phenyl isocyanide.
