उत्तर
Classification of amines:
- Amines are classified as primary (1°), secondary (2°) and tertiary (3°) amines.
- Their structures are obtained in a simple way by replacing one, two, or three hydrogen atoms of NH3 molecule by alkyl/aryl groups.
- The functional group present in primary amines is referred to as an amino group (–NH2).
e.g. Ethylamine [C2H5 – NH2] - The functional group present in secondary amines is referred to as the imino group (>NH).
e.g. Dimethylamine [(CH3)2NH] - The functional group present in tertiary amines is tertiary nitrogen represented as:
e.g. Trimethylamine [(CH3)3N]
