Teflon is a polymer of which of the following monomers?
- ATetrafluoroethylene
- BVinyl chloride
- CChloroprene
- DAcetylene dichloride
- ENone of the above/More than one of the above
Show answer and explanation
Correct answer: (a) Tetrafluoroethylene
Explanation
Teflon is polytetrafluoroethylene (PTFE), a polymer of tetrafluoroethylene (CF₂=CF₂).
It is very slippery, resists heat (up to about 260 °C in use) and is chemically inert, so it is used for non-stick cookware and seals. Vinyl chloride gives PVC, and chloroprene gives neoprene.
