Options:
  • A the chain length of organ silicone polymers can be controlled by adding $\mathrm{Me}_3 \mathrm{SiCl}$
  • B $\mathrm{Me}_3 \mathrm{SiCl}$ improves the quality of the silicone polymer
  • C $\mathrm{Me}_3 \mathrm{SiCl}$ improves the yield of the silicone polymer
  • D $\mathrm{Me}_3 \mathrm{SiCl}$ acts as a catalyst during polymerisation

The correct answer is: the chain length of organ silicone polymers can be controlled by adding $\mathrm{Me}_3 \mathrm{SiCl}$
$\left(\mathrm{CH}_3\right)_3 \mathrm{SiCl}$ is used during polymerisation of organosilicons because the chain length of organosilicon polymers can be controlled by adding $\left(\mathrm{CH}_3\right)_3 \mathrm{SiCl}$ which blocks the ends of silicon polymer. Hence, the correct option is (1).
