The correct match between Item-I and Item-II is
| Item I | Item II |
|---|---|
| (p) High density polythene | (I) Peroxide catalyst |
| (q) Polyacrylonitrile | (II) Condensation at high temperature and pressure |
| (r) Novolac | (III) Ziegler-Natta catalyst |
| (s) Nylon 6 | (IV) Acid or base catalyst |
Options:
Answer:
D
Solution:
| Item I | Item II |
|---|---|
| (p) High density polythene | (III) Ziegler-Natta catalyst |
| (q) Polyacrylonitrile | (I) Peroxide catalyst |
| (r) Novolac | (IV) Acid or base catalyst |
| (s) Nylon 6 | (II) Condensation at high temperature and pressure |
High density polythene is obtained by using Ziegler Natta catalyst. Polyacrylo nitrile is gap obtained by acrylonitrile using peroxide as catalyst. Novolac is obtained in the presence of(or)as catalyst. Nylon-6 is condensation polymer of caprolactam at high temperature and pressure.
