(C) The chain length of silicone polymers is controlled by adding $Me_{3}SiCl$ (trimethylchlorosilane).$Me_{3}SiCl$ acts as a chain terminator because it has only one chlorine atom,which can react with the silanol group to block the end of the polymer chain.The reaction is as follows:$Me_{3}SiCl + H_{2}O \rightarrow Me_{3}SiOH + HCl$This $Me_{3}SiOH$ unit caps the growing polymer chain,preventing further polymerization and thus controlling the chain length.

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