n-Butyl bromide has higher boiling point than t-butyl bromide. Give reasons.

Explanation

To explain why n-butyl bromide has a higher boiling point than t-butyl bromide, we can break down the reasoning into clear steps:

### Step 1: Understand the Structures
- **n-Butyl bromide** has a straight-chain structure: CH3-CH2-CH2-CH2-Br.
- **t-Butyl bromide** has a branched structure: (CH3)3C-Br.

### Step 2: Analyze the Molecular Mass
- Both n-butyl bromide and t-butyl bromide have the same molecular formula (C4H9Br), meaning they have similar molecular masses. Therefore, mass alone does not account for the difference in boiling points.
