4 Terylene

JEE - 2016

CHXII15:POLYMERS

324934 Which of the following method is suitable to prepare monomer of PVC ?

1

{CH}_{2} = {CH}_{2} + {Cl}_{2} \to

2

{CH}_{2} = {CH}_{2} + HCl \to

3

CH = {CH}_{2} + {Cl}_{2} \to

4

HC \equiv CH + HCl \to

Explanation:

Monomer of pvc is vinylchloride $({CH}_{2} = CH - Cl)$
supporting img
$HC \equiv \underset{↓}{CH} + HCl$
$C H_{2} = C H_{2} + HCl \to C H_{3} C H_{2} Cl$
$C H_{2} = CH - Cl$
