Question

Term tertiary, secondary and primary amine represents the:

• A. degree of uunsaturation
• B. number of amino groups
• C. nature of C atom
• D. degree of substitution on nitrogen

Answer 1

Answer: (D)

Amines are derivatives of ammonia.
If one hydrogen of ammonia is replaced by an alkyl group, it is called a primary amine
If two hydrogens of ammonia are replaced by alkyl groups, it is called a secondary amine
If three hydrogens of ammonia are replaced by alkyl groups, it is called a tertiary amine
So, tertiary, secondary, and primary amine represents the degree of substitution on the nitrogen
