Interpretation:
The difference between primary, secondary, and tertiary
Concept introduction:
Amines are nitrogen-containing organic compounds. The general formula of amines is
Answer to Problem 16.1E
In primary amines, nitrogen atom is attached to one alkyl or aryl group. In secondary amines, nitrogen atom is attached to two alkyl or aryl groups. In tertiary amines, nitrogen atom is attached to three alkyl or aryl groups.
Explanation of Solution
In primary amines, one of the hydrogen atoms of ammonia is replaced by alkyl or aryl group. The nitrogen atom is attached to one alkyl or aryl group in primary amine.
In secondary amines, two of the hydrogen atoms of ammonia are replaced by alkyl or aryl group. The nitrogen atom is attached to the two alkyl or aryl groups in secondary amine.
In tertiary amines, all hydrogen atoms of ammonia are replaced by alkyl or aryl group. The nitrogen atom is attached to three alkyl or aryl groups in tertiary amine.
In primary amines, nitrogen atom is attached to one alkyl or aryl group. In secondary amines, nitrogen atom is attached to two alkyl or aryl groups. In tertiary amines, nitrogen atom is attached to three alkyl or aryl groups.
