List-I:
(A) Nylon 6
(B) Vulcanized Rubber
(C) cis-1,4-polyisoprene
(D) Polychloroprene
List-II:
(I) Natural Rubber
(II) Cross Linked
(III) Caprolactam
(IV) Neoprene
Answer: A → III, B → II, C → I, D → IV
Solution
Nylon-6 is a polyamide obtained by the ring-opening polymerisation of caprolactam, so it is matched with caprolactam. Vulcanised rubber is produced by heating rubber with sulphur, which introduces sulphur cross-links between the chains, so it is matched with cross-linked. cis-1,4-Polyisoprene is the chemical form of natural rubber, so these are matched. Polychloroprene is the polymer of chloroprene and is known commercially as neoprene, so it is matched with neoprene. The correct pairing is A–III, B–II, C–I and D–IV.
