Me_{3}SiCl is used during polymerisation of organic silicones because

(i) the chain length of organic silicone polymers can be controlled by adding Me_{3}SiCl

(ii) Me_{3}SiCl blocks the end terminal of a silicone polymer

(iii) Me_{3}SiCl  improves the quality and yield of the polymer

(iv) Me_{3}SiCl acts as a catalyst during polymerisation

The answer is the option (i) The chain length of organic silicone polymers can be controlled by adding Me3 and (ii) Me_{3}SiCl blocks the end terminal of a silicone polymer.

The length of the chain can be in control by increasing the amount of Me_{3}SiCl, which helps in blocking of the polymer ends.
