1.

The silicons ae organosilicon polymers containing `Si-O-Si` linkage. They are usually prepared by hydrolysis of alkylchlorosilanes, the silanols formed as intermediates on hydrolysis condense by intermolecular elimination of water with the formation of `Si-O-Si` linkage To get the silicone of `R_(3)Si-(O SiR_(2)_(n)-SiR_(3)`, having 4 SiO-Si linkage, the unit taken isA. 3 unit of `R_(3)SiCl` and 2 unit `R_(2)SiCl_(2)`B. 3 unit of `R_(2)SiCl_(2)` and 2 unit `R_(3)SiCl`C. 2 unit of `R_(2)SiCl_(2)` and 2 unit `R_(3)SiCl`D. 4 unit of `R_(3)SiCl_(2)` and 2 unit `R_(3)SiCl`
