Ethyl bromide to ethane.

Explanation

To convert ethyl bromide (CH3CH2Br) to ethane (CH3CH3), we can follow these steps:

### Step 1: Convert Ethyl Bromide to Ethanol
1. **React Ethyl Bromide with Aqueous KOH**:
- Ethyl bromide (CH3CH2Br) is treated with aqueous potassium hydroxide (KOH).
- The hydroxide ion (OH⁻) from KOH replaces the bromine ion (Br⁻) in ethyl bromide.
- The reaction can be represented as:
