question_answer 1)

  The \[M{{e}_{3}}SiCl\] is used during polymerisation of organo- silicones because: (a) the chain length of organosilicone polymers can be controlled by adding \[M{{e}_{3}}SiCl\] (b) \[M{{e}_{3}}SiCl\]block the end terminal of silicone polymer (c) \[M{{e}_{3}}SiCl\]improves the quality and yield of the polymer (d) \[M{{e}_{3}}SiCl\]acts as a catalyst during polymerization

Answer:

  (a, b) For explanation see the answer of question 8.
