Question:
Poly Tetra Fluoro Ethylene (PTFE) is known as
Poly Tetra Fluoro Ethylene (PTFE) is known as
Show Hint
The presence of highly electronegative fluorine atoms tightly shielding the carbon backbone gives Teflon (PTFE) its signature non-stick, hydrophobic, and thermal resistance characteristics.

The Correct Option is B
Solution and Explanation
Concept:
Poly Tetra Fluoro Ethylene (PTFE) is a high-molecular-weight synthetic fluoropolymer consisting entirely of carbon and fluorine atoms. Its chemical structure is represented as:
\[
\text{--}\big(\text{CF}_2\text{--CF}_2\big)_n\text{--}
\]
Step 1: Matching with the correct commercial trade name.
The globally recognized commercial trade name for PTFE is Teflon (originally registered by DuPont).
Step 2: Explaining its exceptional material attributes.
The carbon-fluorine ($\text{C--F}$) chemical bond has an exceptionally high bond dissociation energy, which makes PTFE virtually inert to chemical attack by aggressive acids or bases. It also gives the material a high melting point ($327^\circ\text{C}$) and an extremely low coefficient of friction, which is why it is widely used for non-stick cookware coatings, industrial gaskets, and corrosion-resistant seals. This matches option (2).
Step 3: Clarifying alternative options.
• Bakelite: Phenol-formaldehyde thermosetting resin.
• Celluloid: A plasticized mixture of nitrocellulose and camphor.
• Dacron: A trade name for polyethylene terephthalate (PET) polyester fiber.
