Options

  1. Athe chain length of organ silicone polymers can be controlled by adding Me ₃ SiCl
  2. BMe ₃ SiCl improves the quality of the silicone polymer
  3. CMe ₃ SiCl improves the yield of the silicone polymer
  4. DMe ₃ SiCl acts as a catalyst during polymerisation

Correct answer

A. the chain length of organ silicone polymers can be controlled by adding Me ₃ SiCl

Step-by-step solution

( CH ₃ )₃ SiCl is used during polymerisation of organosilicons because the chain length of organosilicon polymers can be controlled by adding ( CH ₃ )₃ SiCl which blocks the ends of silicon polymer. Hence, the correct option is (1).
