Draw the structures of the monomers of the following polymers:
(i) Polythene
(ii) PVC
(iii) Teflon

Explanation

To solve the question of drawing the structures of the monomers for the given polymers, we will identify each polymer and its corresponding monomer, then draw the structures step by step.

### Step 1: Identify the monomer for Polythene
- **Polymer**: Polythene
- **Monomer**: Ethene

**Structure of Ethene**:
- Ethene has the formula C2H4, which can be represented as:
...
