MCQ
Which is not monomer for a high molecular mass silicone polymer
  • A
    $PhSiCl_3$
  • B
    $MeSiCl_3$
  • C
    $Me_2SiCl_2$
  • ✓
    $Me_3SiCl$
✓

Answer

Correct option: D.
$Me_3SiCl$
d
$\mathrm{MeSiCl}_{3}, \mathrm{Me}_{2} \mathrm{SiCl}_{2}$ and $\mathrm{PhSiCl}_{3}$ are monomers for a high molecular mass silicone polymer.

However, Me $_{3} \mathrm{SiCl}$ 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.

Hence, the correct answer is option D.
