Which among the following isomers of hexane has the higest boiling points ?

Options

A. `CH_3CH_2-CH_2CH_2-CH_2CH_3`
B. `CH_3-CH-underset(CH_3)underset(|)CH_2-CH_3`
C. `H_3-CH_2-C-underset(CH_3)underset(|)overset(CH_3)overset(|)(CH"_3`
D. `CH_2-CH-underset(CH_3)underset(|)"CH"-CH-underset(CH_3)underset(|)(CH_3`

Explanation

To determine which isomer of hexane has the highest boiling point, we need to analyze the structure of the isomers and how branching affects boiling points.

### Step-by-Step Solution:

1. **Understand the Isomers of Hexane**:
Hexane (C6H14) has five structural isomers:
- n-Hexane (unbranched)
- 2-Methylpentane
