The number of H involved in the conversion of nitrobenzene to hydrazobenzene are :
Open in App
Solution
The correct option is D 8
When nitrobenzene is reduced, nitrosobenzene and N-phenylhydroxylamine are obtained.
These intermediates react to form azoxybenzene. Azoxybenzene, on further reduction, forms azobenzene and hydrazobenzene.
The reduction of nitrobenzene to nitrosobenzene requires 2H.
The reduction of nitrobenzene to phenylhydroxylamine requires 2H.
The reduction of azoxybenzene to azobenzene requires 2H.
The reduction of azobenzene to hydrazobenzene requires 2H.
Hence, the number of H involved in the conversion of nitrobenzene to hydrazobenzene are 8.
