Q2 / 90 · JEE Main 2021 (24 Feb Shift 1) · Chemistry

Match List I with List II.

  List I (Monomer Unit)   List II (Polymer)
 (a)  Caprolactum  (i)  Natural rubber
 (b)  2-Chloro-1,3-butadiene  (ii)  Buna-N
 (c)  Isoprene  (iii)  Nylon 6
 (d)  Acrylonitrile  (iv)  Neoprene

Choose the correct answer from the options given below:

  • Correct answer
    A
    a→iii,b→iv,c→i,d→ii
  • B
    a→i,b→ii,c→iii,d→iv
  • C
    a→ii,b→i,c→iv,d→iii
  • D
    a→iv,b→iii,c→ii,d→i

Solution

(a) FigureCaprolactum is the monomeric unit of polymer Nylon-6.

(b) 2-Chlorobuta-1, 3-diene is the monomeric unit of polymer neoprene.
(c) Isoprene is the monomeric unit of polymer natural rubber.
(d) CH2=CH-CN (Acrylonitrile) is one of the monomeric unit of polymer Buna-N.

Hence, the correct answer is option: 'A'.
