Question
The correct match between Item - I and Item - II is:
| Item - I | Item - II | ||
| (a) | High density polythene | (I) | Peroxide catalyst |
| (b) | Polyacrylonitrile | (II) | Condensation at high temperature & pressure |
| (c) | Novolac | (III) | Ziegler-Natta catalyst |
| (d) | Nylon 6 | (IV) | Acid or base catalyst |

Correct answer
B
Step-by-step explanation
Ziegler-Natta is used in the production of high-density polymer.
The addition polymerisation of Acrylonitrite in presence of a peroxide catalyst leads to the formation of Polyacrylonitrile
Nylon - 6 is a condensation polymer made from caprolactum
Novolac is the linear product of phenol-formaldehyde which is produced by condensation reactions in the presence of either acid or base.
