The correct match between Item - I and Item - II is: Item - I Item...

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

Options

  1. A(a)→(IV),(b)→(II),(c)→(I),(d)→(III)\left(a\right) \to \left(IV\right), \left(b\right) \to ( II ) , ( c ) \to ( I ) , ( d ) \to ( III )
  2. B(a)→(III),(b)→(I),(c)→(IV),(d)→(II)( a ) \to \left(III\right), ( b ) \to ( I ) , ( c ) \to ( IV ) , ( d ) \to ( II )
  3. C(a)→(III),(b)→(I),(c)→(II),(d)→(IV)( a ) \to \left(III\right), ( b ) \to ( I ) , ( c ) \to ( II ) , ( d ) \to ( IV )
  4. D(a)→(II),(b)→(IV),(c)→(I),(d)→(III)( a ) \to \left(II\right), \left(b\right) \to \left(IV\right), \left(c\right) \to \left(I\right), \left(d\right) \to \left(III\right)

Correct answer

B. (a)→(III),(b)→(I),(c)→(IV),(d)→(II)( a ) \to \left(III\right), ( b ) \to ( I ) , ( c ) \to ( IV ) , ( d ) \to ( II )

Step-by-step solution

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.
