How will you convert ethane to ethene

Explanation

To convert ethane (C2H6) to ethene (C2H4), we can follow these steps:

### Step 1: Halogenation of Ethane
- Ethane (C2H6) is treated with bromine (Br2) in the presence of light (hν). This process is a free radical substitution reaction.
- The bromine molecule (Br2) splits into two bromine radicals (Br•), which then react with ethane to form bromoethane (C2H5Br).

**Reaction:**
\[ \text{C}_2\text{H}_6 + \text{Br}_2 \xrightarrow{h\nu} \text{C}_2\text{H}_5\text{Br} + \text{HBr} \]
