Question:
Which from following polymers is obtained from $C_{2}F_{4}$?
Which from following polymers is obtained from $C_{2}F_{4}$?
Show Hint
Logic Tip: The prefix "tetrafluoro-" gives it away! "Poly-tetrafluoro-ethylene" yields the acronym PTFE, which is globally known by its brand name, Teflon, widely used for non-stick cookware coatings.

The Correct Option is D
Solution and Explanation
Concept:
Addition polymers are formed by the repeated addition of monomer molecules possessing double or triple bonds. To identify the polymer, look at the chemical name of the monomer unit provided in the question.
Step 1: Identify the monomer $C_2F_4$.
The chemical formula $C_2F_4$ can be drawn structurally as $CF_2=CF_2$. This compound is an ethylene molecule where all four hydrogen atoms have been replaced by fluorine atoms. Its chemical name is tetrafluoroethylene.
Step 2: Match the monomer to its corresponding polymer.
When tetrafluoroethylene undergoes addition polymerization at high pressures in the presence of a free radical catalyst, it forms polytetrafluoroethylene (PTFE). $$n(CF_2=CF_2) \xrightarrow{\text{Polymerization \text{--}[CF_2-CF_2]_n\text{--}$$ The commercial name for polytetrafluoroethylene is Teflon.
Step 3: Verify the other options for clarity.

Step 3: Verify the other options for clarity.
- PVC (Polyvinyl chloride) is made from vinyl chloride ($CH_2=CHCl$).
- Polyisobutylene is made from isobutylene.
- Polyacrylonitrile (PAN) is made from acrylonitrile ($CH_2=CH-CN$).
