Ethene to chloroethane

Explanation

To convert ethene (C2H4) to chloroethane (C2H5Cl), we can follow these steps:

### Step 1: Identify the Reactants
- We start with ethene (C2H4), which is an alkene with a double bond between the two carbon atoms.

### Step 2: Understand the Reaction
- The conversion involves the addition of hydrochloric acid (HCl) to ethene. This is an electrophilic addition reaction where HCl adds across the double bond of ethene.
