Write the monomers used for getting the following polymers.
(i) Polyvinyl chloride
(ii) Teflon
(iii) Bakelite.

Answer

To answer the question regarding the monomers used for the specified polymers, we will identify the monomers for each polymer listed.

### Step-by-Step Solution:

1. **Polyvinyl Chloride (PVC)**:
- The monomer used to produce Polyvinyl Chloride is **Vinyl Chloride**.
- The chemical structure of Vinyl Chloride is represented as:
\[ \text{CH}_2=\text{CHCl} \]

2. **Teflon**:
- The monomer used to produce Teflon is **Tetrafluoroethylene**.
- The chemical structure of Tetrafluoroethylene is represented as:
\[ \text{CF}_2=\text{CF}_2 \]

3. **Bakelite**:
- Bakelite is produced from two monomers: **Phenol** and **Formaldehyde**.
- The chemical structure of Phenol is:
\[ \text{C}_6\text{H}_5\text{OH} \]
- The chemical structure of Formaldehyde is:
\[ \text{HCHO} \]

### Summary of Monomers:
- **Polyvinyl Chloride (PVC)**: Vinyl Chloride (CH₂=CHCl)
- **Teflon**: Tetrafluoroethylene (CF₂=CF₂)
- **Bakelite**: Phenol (C₆H₅OH) and Formaldehyde (HCHO)
