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

Explanation

To solve the problem of identifying the monomers of the given polymers, we will go through each polymer step by step and draw the structures of their respective monomers.

### Step 1: Identify the monomer of Polythene
- **Polymer**: Polythene
- **Monomer**: Ethene (also known as Ethylene)
- **Structure of Ethene**: Ethene has the molecular formula C2H4. The structure can be represented as follows:
