Question

The straight chain polymer is formed by :

Moderate

A

hydrolysis of CH₃SiCl₃ followed by condensation polymerization
B

hydrolysis of (CH₃)₄Si followed by addition polymerization
C

hydrolysis of (CH₃)₂SiCl₂, followed by condensation polymerization
D

hydrolysis of (CH₃)₃SiCI followed by condensation polymerization

Solution

Hydrolysis of substituted chlorosilanes yields corresponding silanols which undergo polymerization. Out of the given chlorosilanes, only (CH₃)₂SiCl₂ will give linear polymer on hydrolysis followed by polymerization
