Ethene forms an addition product with chlorine. Name this addition product and write its structural formula.

Explanation

To solve the question, we need to identify the addition product formed when ethene reacts with chlorine and write its structural formula. Here’s a step-by-step solution:

### Step 1: Identify the reactants
- The reactant in this case is ethene, which has the molecular formula C₂H₄. Ethene is an unsaturated hydrocarbon that contains a carbon-carbon double bond.

### Step 2: Understand the addition reaction
- In an addition reaction, two reactants combine to form a single product. Ethene can react with chlorine (Cl₂) in a process known as halogenation.
