Which of the following polymers are correctly matched with their monomers?

1. Neoprene -> Chloroprene
2. Natural rubber -> Isoprene
3. Teflon -> Tetrafluoroethene
4. Acrilan -> Acrylonitrile

Correct answer: Neoprene -> Chloroprene

Solution

All four matches are correct: Neoprene is made from chloroprene (2-chloro-1,3-butadiene); Natural rubber is made from isoprene (2-methyl-1,3-butadiene); Teflon is made from tetrafluoroethene (CF2=CF2); Acrilan is made from acrylonitrile (CH2=CH-CN). This is a multi-correct question and all options are valid.
