MCQ
Term tertiary, secondary and primary amine represents the:
  • A
    Number of amino groups
  • B
    Nature of $C$ atom
  • ✓
    Degree of substitution on nitrogen
  • D
    Degree of uunsaturation
✓

Answer

Correct option: C.
Degree of substitution on nitrogen
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.
