Question

Match the polymers given in Column I with their chemical names given in Column II.

Column I Column II
(i) Nylon 6 (a) Polyvinyl chloride
(ii) PVC (b) Polyacrylonitrile
(iii) Acrilan (c) Polycaprolactum
(iv) Natural rubber (d) Low-density polythene
(v) LDP (e) cis-polyisoprene
Match the Columns

Solution

Column I Column II
(i) Nylon 6 (c) Polycaprolactum
(ii) PVC (a) Polyvinyl chloride
(iii) Acrilan (b) Polyacrylonitrile
(iv) Natural rubber (e) cis-polyisoprene
(v) LDP (d) Low-density polythene

Explanation:

Column I Column II
(i) Nylon 6 It is obtained by heating caprolactum with water at a high temperature.
(ii) PVC Polymer of vinyl chloride.
(iii) Acrilan The addition polymerisation of acrylonitrile in presence of a peroxide catalyst leads to the formation of polyacrylonitrile.
(iv) Natural rubber Natural rubber may be considered as a linear polymer of isoprene (2-methyl-1, 3-butadiene) and is also called as cis - 1, 4 - polyisoprene.
(v) LDP The low-density polythene (LDP) is obtained through the free radical addition and H-atom abstraction. It has highly branched structure.
