Among the following substituted silanes, the one which will give rise to cross linked silicone polymer on hydrolysis is?

Options

A. `RSiCl_(3)`
B. `R_(2)SiCl_(2)`
C. `R_(3)SiCl`
D. `R_(4)Si`

Answer

A

Explanation

`R_(2)SiCl_(2)` can form linear polymer due to two replaceable Cl atom. `R_(3)SiCl` can terminate the reaction because it has only one replaceable Cl atom upon hydrolysis Cl atom is replaced by -OH group) and thus it cannot polymerise.
`R SiCl_(3)` has 3 replaceable Cl atoms which upon hydrolysis can form cross linked silicone polymer.
