Question

Nitroethane and nitrobenzene are reduced separately by lithium aluminium hydride the products formed respectively are

Answer 1

With nitroethane, the product formed is ethyl amine.

With nitrobenzene the product formed is azobenzene.

Answer 2

NITROETHANE IS REDUCED BY LITHIUM ALUMINUM HYDRIDE TO ETHANE AMINE.

NITROBENZENE IS REDUCED TO AZOBENZENE BY LITHIUM ALUMINUM HYDRIDE.

Explanation:

• Lithium aluminum hydride is a strong reducing agent.
• It reduces aldehydes, ketones, acids, acid chlorides, to alcohol. And it reduces aliphatic nitro compounds to amines,
• NITROETHANE is an aliphatic compound so it will be reduced to ethane amine.
• Whereas nitrobenzene will not form aniline($C_{6} H_{5} NH_{2}$).
• When nitrobenzene is treated with $LiAlH_{4}$ it forms aniline and nitrosobenzene which react together to form azobenzene.
