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

Solution:

$MeSiCl_{3},Me_{2}SiCl_{2}$ and $PhSiCl_{3}$ are monomers for a high molecular mass silicone polymer.

However, $Me_{3}SiCl$ is not a monomer for a high molecular mass silicone polymer as it contains only one Cl atom and at best, it can form a dimer only.

As $Me_{3}SiCl$ on hydrolysis gives $Me_{3}SiOH$ which can't undergo polymerisation.
