Question

Tetrafluoroethylene is known as

• A. Perspex
• B. Nylon-66
• C. Polyester
• D. Teflon

Hint:

Tetrafluoroethylene (\( \text{C}_2\text{F}_4 \)) is the monomer for polytetrafluoroethylene (PTFE), commonly known as Teflon, used in non-stick and chemical-resistant applications.

Answer 1

The Correct Option is D

Step 1: Identify tetrafluoroethylene.
Tetrafluoroethylene (TFE) is a chemical compound with the formula \( \text{C}_2\text{F}_4 \). It is a fluorocarbon where all hydrogen atoms in ethylene (\( \text{C}_2\text{H}_4 \)) are replaced by fluorine atoms. TFE is a colorless, flammable gas used primarily as a monomer to produce polymers. Step 2: Determine the polymer associated with tetrafluoroethylene.
Tetrafluoroethylene is polymerized to form polytetrafluoroethylene (PTFE), a fluoropolymer known for its low friction, chemical resistance, and high-temperature stability. PTFE is commonly known by its trade name, Teflon, which is widely used in applications like non-stick coatings, gaskets, and seals. Step 3: Evaluate the options.
Perspex: Perspex is a trade name for polymethyl methacrylate (PMMA), a transparent thermoplastic (acrylic), unrelated to tetrafluoroethylene.
Nylon-66: Nylon-66 is a polyamide made from hexamethylenediamine and adipic acid, not related to tetrafluoroethylene.
Polyester: Polyesters are polymers formed from dicarboxylic acids and diols (e.g., PET from terephthalic acid and ethylene glycol), not tetrafluoroethylene.
Teflon: Teflon is the trade name for polytetrafluoroethylene (PTFE), the polymer of tetrafluoroethylene. Step 4: Select the correct answer.
Tetrafluoroethylene is known as Teflon (as its polymer, PTFE), matching option (4).
