Vedclass · Answer

(A) Silicones are a group of organosilicon polymers,which have $(-R_2SiO-)$ as a repeating unit.The starting materials for the manufacture of silicones are alkyl or aryl substituted silicon chlorides,$R_nSiCl_{(4-n)}$,where $R$ is an alkyl or aryl group.Upon hydrolysis of these alkyl or aryl substituted silicon chlorides,silanols are formed,which undergo condensation polymerization to form silicones.Among the given options,$(CH_3)_2SiCl_2$ is an alkyl-substituted silicon chloride,which on hydrolysis yields $(CH_3)_2Si(OH)_2$,followed by polymerization to form silicones. Therefore,option $A$ is the correct answer.

Which of the following compounds forms silicones on hydrolysis?
