The monomer for Teflon polymer is

Options

A. Monofluoroethene
B. Difluoroethene
C. Trifluoroethene
D. Tetrafluoroethene

Answer

To determine the monomer for the Teflon polymer, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Teflon**: Teflon is a well-known polymer used primarily for its non-stick properties in cookware. Its chemical name is polytetrafluoroethylene (PTFE).

2. **Understand the Structure of Teflon**: Teflon is formed through the polymerization of tetrafluoroethylene. The repeating unit in Teflon consists of carbon and fluorine atoms.

3. **Identify the Monomer**: The monomer that polymerizes to form Teflon is tetrafluoroethylene, which has the chemical formula CF2=CF2. This means that each monomer contains a double bond between two carbon atoms, each bonded to two fluorine atoms.

4. **Write the Polymerization Reaction**: The polymerization of tetrafluoroethylene can be represented as:
\[ n \, \text{CF}_2=\text{CF}_2 \xrightarrow{\text{heat, pressure}} \text{(CF}_2\text{)}_n \]
where 'n' represents the number of repeating units in the polymer chain.

5. **Conclusion**: Based on the above information, we conclude that the monomer for Teflon is tetrafluoroethylene.

### Final Answer:
The monomer for Teflon polymer is **Tetrafluoroethylene**.
