Answer 2

The formation of the secondary and tertiary amine is prevented during the preparation of amine by the alkylation of ammonia. It is tested with the help of Carbyl Amine Test.

Explanation:

• The formation of secondary and tertiary amines fails to undergo the carbylamine test because they react with alcoholic KOH.
• Carbylamine test -
• It is a  test that is used for detecting primary amines.
• In this heating, the substance with chloroform in a basic solution is carried out in the presence of an amine.
