Question

The straight chain polymer is formed by

(a) hydrolysis of CH₃SiCl₃ followed by condensation polymerisation

(b) hydrolysis of (CH₃)₄Si by addition polymerisation 

(c) hydrolysis of (CH₃)₂SiCl₂ followed by condensation polymerisation

(d) hydrolysis of (CH₃)₃SiCl followed by condensation polymerisation

Answer 1

The correct option is : (c) hydrolysis of (CH₃)₂SiCl₂ followed by condensation polymerisation

Explanation:

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