• # question_answer 54)   Silicon has strong tendency to form polymers like silicones. The chain length of silicone polymer can be controlled by adding: (a)$MeSiC{{l}_{3}}$                      (b) $M{{e}_{2}}SiC{{l}_{2}}$                      (c) $M{{e}_{3}}SiCl$                     (d)$M{{e}_{4}}Si$

(c) $M{{e}_{3}}SiCl$on hydrolysis gives a product which consists only one OH group which can form only dimer. Thus, the chain length of the silicone polymer can be controlled by adding$M{{e}_{3}}SiCl$. $M{{e}_{3}}SiCl+{{H}_{2}}O\xrightarrow{{}}M{{e}_{3}}SiOH+HCl$ $M{{e}_{3}}SiCl+HOSiM{{e}_{3}}\xrightarrow{{}}M{{e}_{3}}Si-O-SiM{{e}_{3}}$
