Chloroethane, 2-chloropropane and chloroethene are treated with methoxide. Which is more reactive towards Williamson's synthesis ?

Explanation

To determine which compound is more reactive towards Williamson's synthesis when treated with methoxide, we need to analyze the three compounds: chloroethane, 2-chloropropane, and chloroethene.

### Step-by-Step Solution:

1. **Understanding Williamson's Synthesis**:
Williamson's synthesis involves the reaction of an alkyl halide with an alkoxide ion (in this case, methoxide) to form an ether. The reactivity of the alkyl halide is crucial in this reaction.

2. **Identifying the Types of Halides**:
