Silicones are synthetic polymers containing repeated `R_2 SiO` units . Since the empirical formula is that of a ketone `(R_2 CO)`, the name Silicone has been given to these materials . Silicone can be made into oils , rubbery elastomers and resins . They find a variety of applications because of their chemical inertness , water repelling nature, heat resistance and good electrical insulating property .
Commerically silicon polymers are usually synthesised by the hudrolysis of
` R_2 SiCl_2 [R = Methyl (Me ) or phenyl ( phi)]`
.
If we start with `SiMeCl_3` as the starting material silicones formed is :

D. none of the above

Answer

B

Explanation

`Si Me Cl_3 overset (H_2O) (rarr) Si Me (OH)_3`
.
