Classify the following reactions in one of the reaction type studied in this unit.
`CH_3CH_2 Br + HO^(-) to CH_2 = CH_2 +H_2 O + Br^(-)`

Explanation

To classify the reaction given, let's analyze the provided equation step by step.

**Step 1: Identify the reactants and products.**
The reaction is:
\[ \text{CH}_3\text{CH}_2\text{Br} + \text{HO}^- \rightarrow \text{CH}_2=\text{CH}_2 + \text{H}_2\text{O} + \text{Br}^- \]

- **Reactants:** CH₃CH₂Br (ethyl bromide) and HO⁻ (hydroxide ion).
- **Products:** CH₂=CH₂ (ethylene), H₂O (water), and Br⁻ (bromide ion).
