Q. Which of these is not a monomer for a high molecular mass silicone polymer?
A) MeSiCl₃
B) Me₂SiCl₂
C) Me₃SiCl
D) PhSiCl₃
Explanation
[Solution from source] Me₃SiCl has only one hydrolysable Si–Cl bond, so after hydrolysis it can bond only at one end and acts as a chain stopper. Me₂SiCl₂ forms chains, and MeSiCl₃ and PhSiCl₃ give cross-linking, building high-molecular-mass silicones. Answer (3).
