Explain basic nature of amines.

Explanation

### Step-by-Step Solution:

1. **Definition of Amines**: Amines are organic compounds that contain a nitrogen atom bonded to one or more alkyl or aryl groups. They can be classified based on the number of carbon groups attached to the nitrogen:
- Primary amines (1°): R-NH2
- Secondary amines (2°): R2-NH
- Tertiary amines (3°): R3-N

2. **Basic Nature of Amines**: The basicity of amines is attributed to the presence of a lone pair of electrons on the nitrogen atom. According to Lewis theory, a base is defined as a species that can donate a lone pair of electrons to an electron-deficient species (an electrophile).
