Write the names and structures of the monomers of the following polymers :
(i) Buna-S
(ii) Neoprene
(iii) Nylon-6

Explanation

To solve the question, we will identify the monomers of the given polymers and provide their structures step by step.

### Step 1: Identify the Monomers of Buna-S
- **Monomers**: The two monomers that make up Buna-S are **1,3-butadiene** and **styrene**.

#### Structure of 1,3-butadiene:
1. 1,3-butadiene has 4 carbon atoms.
2. There are double bonds between the 1st and 2nd carbon, and between the 3rd and 4th carbon.
