option B Under hydrolytic conditions, the compound used for the preparation of linear polymer and for chain termination are (CH3)2SiCl2 and (CH3)3SiCl respectively. The hydrolysis of dimethyldichlorosilane produces dimethyl silane diol which on condensation polymerization forms a linear polymer. The hydrolysis of trimethylchlorosilane produces trimethyl silanol which cannot undergo polymerization as it contains only one -OH group. Hence, it is used for chain termination.

(CH3)2SiCl2 for linear polymerization and (CH3)3SiCl for chain termination. Explanation:- Under hydrolytic conditions, the compound used for the preparation of linear polymer and for chain termination are (CH3)2SiCl2 and (CH3)3SiCl respectively. The hydrolysis of dimethyldichlorosilane produces dimethyl silane diol which on condensation polymerization forms a linear polymer. The hydrolysis of trimethylchlorosilane produces trimethyl silanol which cannot undergo polymerization as it contains only one -OH group. Hence, it is used for chain termination.
