Write the reactions for the conversion of ethene to dichloroethane

Explanation

To convert ethene (C2H4) to dichloroethane (C2H4Cl2), we can use two methods: direct chlorination and oxychlorination. Here’s a step-by-step breakdown of both methods:

### Method 1: Direct Chlorination

1. **Starting Material**: Ethene (C2H4)
- Structure: CH2=CH2

2. **Reagent**: Chlorine gas (Cl2) and a catalyst (FeCl3)
