Among all the isomers of pentane which has the lowest boiling point ?

Explanation

To determine which isomer of pentane has the lowest boiling point, we first need to identify the isomers of pentane and then analyze their structures.

### Step-by-Step Solution:

1. **Identify the Isomers of Pentane**:
- Pentane has the molecular formula \( C_5H_{12} \).
- The isomers of pentane are:
- **n-Pentane**: \( CH_3CH_2CH_2CH_2CH_3 \) (straight-chain)
