Match List I with List II:

List I-(Monomer)
(A) Tetrafluoroethylene
(B) Acrylonitrile
(C) Caprolactam
(D) Isoprene

List II-(Polymer)
(i) Orlon
(ii) Natural rubber
(iii) Teflon
(IV) Nylon-6

Choose the correct answer from the options given below:

Answer: A → III, B → I, C → IV, D → II

Solution

Tetrafluoroethylene undergoes addition polymerisation to polytetrafluoroethylene, known as Teflon. Acrylonitrile polymerises to polyacrylonitrile, marketed as Orlon. Caprolactam undergoes ring-opening polymerisation to give Nylon-6. Isoprene (2-methyl-1,3-butadiene) polymerises to cis-polyisoprene, which is natural rubber. The correct pairing is tetrafluoroethylene with Teflon, acrylonitrile with Orlon, caprolactam with Nylon-6, and isoprene with natural rubber.
