Which of these is not a monomer for a high molecular mass silicone polymer?

Options

  1. AMeSiCl ₃
  2. BMe ₂ SiCl ₂
  3. CMe ₃ SiCl
  4. DPhSiCl ₃

Correct answer

C. Me ₃ SiCl

Step-by-step solution

Me ₃ SiCl is not a monomer for a high molecular mass silicone polymer because it generates Me ₃ SiOH when subjected to hydrolysis which contains only one reacting site. Hence, the polymerisation reaction stops just after first step.
