Question

How is aniline Obtained from Benzonitrile

Answer 1

We have to find that how is Aniline obtained from Benzonitrile.

Kindly see the attachment. A complete reaction is shown in the attachment.

We have to treat Aniline with Sodium Nitrite & HCl.

We must treat them at low temperatures.

This reaction gives us diazoniumchloride.

The diazoniumchloride reacts with CuCN and gives us Benzonitrile.

Answer 2

Explanation:

• Aniline is treated with sodium nitrate followed by hydrogen chloride at 273 – 278K to form benzene Diazonium chloride.

• And then treated with copper cyanide to form cyano benzene are also called as Benzonitrile.

• The benzonitile compound is formed by the reaction of Aniline and the benzene diazonium chloride with the presence of Sodium nitrate and the hydrogen chloride.

The chemical reaction that shows the preparation of aniline from Benzonitrile is attached in the below attachment:
