Question

What are the product of reduction of nitrobenzene under different condition

Answer 1

Answer:

In acidic medium if nitro benzene is reduced along with tin and concentrated HCl acid,then it is reduced or converted to aniline. When reduced in alkaline medium,nitro benzene forms some intermediate products like Nitrosobenzene and Phenyl hydroxylamine which undergo bi-molecular condensation reaction

Answer 2

REDUCTION OF NITROBENZENE

Explanation:

Lets see the reduction of nitrobenzene in following medium:

1. In acidic medium

  Nitro benzene is reduced with tin and concentrated HCl ,then it is reduced to aniline

               C₆H₅−NO₂ +6[H]  Sn + HCl   C₆H₅−NH₂  + 2H₂O

2. In alkaline medium

In the presence of alkaline medium some of intermediate products like nitroso benzene   and Phenyl hydroxylamine which undergo bi-molecular condensation reaction

3. In neutral medium

   Nitro benzene is reduced along with Zinc dust, and forms Phenyl hydroxylamine .

                 

                 C₆H₅−NO₂   Zn+NH₄Cl  C₆H₅−N=O   2[H]  C₆H₅−NH−OH
