Match List-I with List-II. List-I (Monomer Unit) (A) Caprolactum (B) 2-Chloro-1,3-butadiene (C) Isoprene (D) Acrylonitrile List-II (Polymer) (i) Natural rubber (ii) Buna-N (iii) Nylon 6 (iv) Neoprene Choose the correct answer from the options given below:

1. (A)-(iv), (B)-(iii), (C)-(ii), (D)-(i)
2. (A)-(ii), (B)-(i), (C)-(iv), (D)-(iii)
3. (A)-(iii), (B)-(iv), (C)-(i), (D)-(ii)
4. (A)-(i), (B)-(ii), (C)-(iii), (D)-(iv)

Correct answer: (A)-(iii), (B)-(iv), (C)-(i), (D)-(ii)

Solution

Caprolactam -> Nylon 6 (iii); 2-chloro-1,3-butadiene (chloroprene) -> Neoprene (iv); isoprene -> Natural rubber (i); acrylonitrile -> Buna-N (ii). So (A)-(iii), (B)-(iv), (C)-(i), (D)-(ii).
