Question

Which of the following is fully Fluorinated polymer?

• A. PVC
• B. Teflon
• C. neoprene
• D. Buna-S

Hint:

Teflon is polytetrafluoroethylene, with every hydrogen replaced by fluorine.

Answer 1

The Correct Option is B

Step 1: Approach
Look at the monomer of each polymer.

Step 2: Monomers
PVC: vinyl chloride, $\text{CH}_2\text{=CHCl}$. Teflon: tetrafluoroethylene, $\text{CF}_2\text{=CF}_2$. Neoprene: chloroprene, $\text{CH}_2\text{=CCl-CH=CH}_2$. Buna-S: butadiene with styrene.

Step 3: Conclusion
Only the Teflon monomer carries fluorine on every position, option (B).

Final Answer:
Teflon is built from $\text{CF}_2\text{=CF}_2$ and is fully fluorinated, option (B). \[ \boxed{\text{Teflon}} \]
