Question

17. In acid medium nitrobenzene is reduced to aniline as
shown in the reaction
C6H5 - NO2 + 6[H] → C6H5 - NH2 + 2H2O
The reducing agent used in this reaction is .
(A) LiAlH4
(B) Sn/HCI
(C) Na/alcohol
(D) H2/Ni​

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.
