Question

\( \text{F}_2\text{C} = \text{CF}_2 \) is a monomer of which of the following?

• A. Teflon
• B. Glyptal
• C. Nylon-6
• D. Buna-S

Hint:

Teflon is made from the polymerization of tetrafluoroethylene (C\(_2\)F\(_4\)), known for its non-stick properties.

Answer 1

The Correct Option is A

Step 1: Understanding the structure.
The monomer \( \text{F}_2\text{C} = \text{CF}_2 \) is the repeating unit of Teflon (polytetrafluoroethylene, PTFE), a polymer known for its high resistance to chemicals and heat. Step 2: Analysis of options.
(A) Teflon: Correct — The polymerization of \( \text{F}_2\text{C} = \text{CF}_2 \) leads to the formation of Teflon.
(B) Glyptal: Glyptal is a polyester resin used in paints and coatings, and is not made from the given monomer.
(C) Nylon-6: Nylon-6 is made from caprolactam, not from the given monomer.
(D) Buna-S: Buna-S is a synthetic rubber made from butadiene and styrene, not from the given monomer.
Step 3: Conclusion.
The correct answer is (A) because \( \text{F}_2\text{C} = \text{CF}_2 \) is the monomer for Teflon.
