Question

Silicon has a strong tendency to form polymers like silicones. The chain length of silicone polymer can be controlled by adding.

A

$\mathrm { MeSiCl } _ { 3 }$

B

$\mathrm { Me } _ { 2 } \mathrm { SiCl } _ { 2 }$

C

$\mathrm { Me } _ { 3 } \mathrm { SiCl }$

D

$\mathrm { Me } _ { 4 } \mathrm { Si }$

Answer

$\mathrm { Me } _ { 3 } \mathrm { SiCl }$

Explanation

Solution

: The chain length of silicone polymer can be controlled by adding which blocks the ends as shown below:

$\left( \mathrm { CH } _ { 3 } \right) _ { 3 } \mathrm { SiCl } \xrightarrow [ - \mathrm { HCl } ] { \mathrm { H } _ { 2 } \mathrm { O } } \left( \mathrm { CH } _ { 3 } \right) _ { 3 } \mathrm { SiOH }$
