Nitrobenzene is reduced with $Sn / HCl$ and the product, after neutralisation, is warmed with chloroform and alcoholic $KOH$ . The final product, which has a very unpleasant smell, is

Anitrosobenzene
Bphenyl isocyanide
Cbenzonitrile
Dchlorobenzene

Answer: B

Sn / HCl

reduces

C X_{6} H X_{5} NO X_{2}

to aniline, a primary amine. Primary amines with

CHCl X_{3}

and alcoholic

KOH

give isocyanides in the carbylamine reaction:

C X_{6} H X_{5} NH X_{2} C X_{6} H X_{5} NC

, a foul-smelling compound.
