Question

Teflon is a polymer of which of the following monomers?
1. Tetrafluoroethylene
2. Vinyl chloride
3. Chloroprene
4. Acetylene dichloride
5. None of the above/More than one of the above

Answer 1

Correct Answer - Option 1 : Tetrafluoroethylene

The correct answer is Tetrafluoroethylene.

• Teflon is a polymer of Tetrafluoroethylene.
• Tetrafluoroethylene:
  • Tetrafluoroethylene (TFE) is a fluorocarbon having the chemical formula C2F4.
  • It is the simplest perfluorinated alkene.
  • This gaseous species is used majorly in the industrial preparation of polymers.
  • Tetrafluoroethylene is a colourless, odourless gas.

• Vinyl chloride:
  • This colourless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC).
  • Vinyl chloride, also called chloroethylene, a colourless, flammable, toxic gas belonging to the family of organohalogen compounds and used principally in making polyvinyl chloride, or PVC, a widely used plastic with numerous applications.
• Chloroprene:
  • Chloroprene, the monomer used in the formation of the elastomer neoprene, is prepared from vinylacetylene by this reaction.
  • Neoprene is the common name for the polymers of chloroprene (2-chloro-1,3-butadiene).
  • These are produced by emulsion polymerization.
• Acetylene dichloride:
  • Almost the entire production of the compound is consumed in manufacturing chlorinated solvents, especially trichloroethylene and tetrachloroethylene.
  • It has minor uses as a solvent and as an insecticide, particularly against the greenhouse whitefly.
  •  It is made by the reaction of acetylene and chlorine.
  • Its polymer is Vinyl Chloride.
