Write the names and structures of the monomers of the following polymers :
(i) Polystyrene (ii) Nylon-6, 6 (iii) Terylene

Explanation

To solve the question, we need to identify the monomers of the given polymers and provide their structures. Let's break it down step by step.

### Step 1: Identify the Monomer of Polystyrene
- **Monomer Name**: Styrene
- **Structure**: The structure of styrene consists of a benzene ring (C6H5) attached to a vinyl group (C=C). The complete structure can be represented as:

\[
\text{C}_6\text{H}_5\text{CH}=\text{CH}_2
