Write an account of `SiCl_(4)`

Explanation

`to` Silicon tetrachloride `(SiCl_(4))` is also called as tetra chloro silico methane.
`to SiCl_(4)` , can acts as Lewis acid due to availability of 3d orbital in .S!.
. `to SiCl_(4)` undergoes hydrolysis due to presence of vacant 3d-orbital. Here water molecules forms dative bonds with empty 3d-orbitals of Si-atom.
Uses :
`to SiCl_(4)` and `NH_(3)` mixture used to produce smoke screens
`to` Ultra pure Silicon is used to make transistors,
` SiO_(2)` prepared from `SiCl_(4)` used in epoxypaints, resis etc.
