| Column-A | Column-B |
| Nylon 6 | Natural Rubber |
| Vulcanized Rubber | Cross Linked |
| cis-1,4-polyisoprene | Caprolactam |
| Polychloroprene | Neoprene. |
Choose the correct answer from option given below
Solution:
a) Nylon 6 is synthesized from Caprolactam, hence a→III
b) Vulcanized Rubber involves cross-linking, hence b→II
c) cis–1,4–polyisoprene is the polymer form of Natural Rubber, hence c→I
d) Polychloroprene is commercially known as Neoprene, hence d→IV
Therefore, the correct matching is option (3).
