Vedclass · Answer

(B) Silicones are synthetic organosilicon polymers with the general formula $(R_2SiO)_n$. They are produced by the hydrolysis of alkyl-substituted chlorosilanes. To control the chain length of the silicone polymer,a monofunctional unit like $R_3SiCl$ is added. This unit acts as a chain terminator because it can only form one siloxane bond,preventing further polymerization at that end of the chain.

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