Which specific chlorosilane derivative acts strictly as a chain-terminating unit during the synthesi — 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 silicone chain, it structurally blocks further polymerization at that end, effectively acting as a chain stopper.
