Answer:-

Amines are nitrogen-containing organic compounds having basic character.

Amine Classification:

• Amines are categorized into primary (1°), secondary (2°), and tertiary (3°) amines.

ii. Structural Derivation:

• These amine structures are derived by replacing one, two, or three hydrogen atoms of an NH3 molecule with alkyl or aryl groups.

iii. Secondary and Tertiary Amines Classification:

• Secondary and tertiary amines can be further divided into simple (symmetrical) amines and mixed (unsymmetrical) amines.

iv. Simple and Mixed Amines:

• In a simple amine, all alkyl or aryl groups attached to nitrogen are the same. Conversely, if these groups are different, the amine is considered mixed.

v. Major Amine Classes:

• Amines are also broadly classified into two major categories: aliphatic and aromatic amines, based on the nature of the groups attached to the nitrogen atom.
