Which out of isomeric amines has highest boiling point and why?

Explanation

To determine which isomeric amine has the highest boiling point, we will analyze the isomeric amines and their properties, particularly focusing on hydrogen bonding.

### Step-by-Step Solution:

1. **Identify the Isomeric Amines**:
The isomeric amines of butane are:
- 1-aminobutane (n-butylamine)
- 2-aminobutane (sec-butylamine)
