Options

A. mono chlortifluoroethylene
B. tetrafluoroethylene
C. chloroprene
D. vinyl chloride

Answer

To solve the question regarding the polymer that is resistant to heat and chemical attack and is used for coating articles and cookware to make them non-sticky, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Characteristics of the Polymer**:
- The polymer is resistant to heat and chemical attack.
- It is used for coating cookware to make them non-sticky.

2. **Recall Common Polymers Used in Cookware**:
- One well-known polymer that fits these characteristics is Teflon.

3. **Determine the Monomer of Teflon**:
- Teflon is the commercial name for polytetrafluoroethylene (PTFE).
- The monomer used to produce Teflon is tetrafluoroethylene.

4. **Chemical Structure of the Monomer**:
- Tetrafluoroethylene has the chemical formula C2F4, which consists of two carbon atoms and four fluorine atoms.
- Its structure can be represented as:
\[ \text{CF}_2= \text{CF}_2 \]
- This indicates a double bond between the two carbon atoms.

5. **Polymerization Process**:
- When tetrafluoroethylene undergoes polymerization, it forms long chains of polytetrafluoroethylene (Teflon), which exhibits the desired properties of heat resistance and non-stickiness.

6. **Conclusion**:
- Therefore, the monomer of the polymer used for non-sticky cookware (Teflon) is tetrafluoroethylene.

### Final Answer:
The monomer of the polymer is **Tetrafluoroethylene**.
