Question

Nitrobenzene when reduced with tin and hydrochloric acid, i.e., in acidic medium, the product formes is:

• A. Aniline
• B. Benzene
• C. Both a and b
• D. None of these

Answer 1

The correct option is A Aniline

Nitrobenzene is reduced to phenylammonium ions using a mixture of tin and concentrated hydrochloric acid. The mixture is heated under reflux in a boiling water bath for about half an hour.

Under the acidic conditions, rather than getting phenylamine directly, you instead get phenylammonium ions formed.
