\( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl} \) is used during polymerization of organosilicons because
- A The chain length of organosilicon polymers can be controlled by adding \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl} \)
- B \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl} \) improves the quality and yield of the polymer
- C \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl} \) does not block the end terminal of silicone polymer
- D \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl} \) acts as a catalyst during polymerization
Answer & Solution
Correct Answer
(A) The chain length of organosilicon polymers can be controlled by adding \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl} \)
Step-by-step Solution
Detailed explanation
Silicones are the groups of organosilicon polymers which have \( -\left(R_{2} \mathrm{SiO}\right)- \) as a repeating unit. The chain length of the
polymer can be controlled by adding \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl} \) which blocks the ends.
Silicone
polymer can be controlled by adding \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{SiCl} \) which blocks the ends.
