Concept introduction:
Amines are the hydrocabons which have nitrogen
(1) Primary Amines: The nitrogen atoms is substituted by one alkyl group and two hydrogen atoms are also attached to nitrogen atom is called as primary amine. For example,
(2) Secondary Amines: The nitrogen atoms is substituted by two alkyl groups and one hydrogen atom is also attached to nitrogen atom is called as secondary amine.
(3) Tertiary Amines: The nitrogen atoms is substituted by three alkyl groups and no hydrogen atom is attached to nitrogen atom is called as tertiary amine.
