Which specific organochlorosilane derivative is used as a chain-terminating unit (chain stopper) dur — p Block Elements Chemistry Question

💡 Solution & Explanation

Hydrolysis of $R_3SiCl$ yields $R_3SiOH$, which possesses only one active $-OH$ group. When it condenses with a growing linear silicone chain, it blocks further polymerization at that end, acting as a chain stopper.
