Reaction of chloride of 4th A group
Reaction of a compound with water is called hydrolysis.During hydrolysis, Si atoms of the chlorides make up of their empty d-orbitals in their valence shells to form coordinates bonds with water molecules.
However, C is in period 2 does not have d-orbitals in its valence shell to form coordinate bond with water and is not hydrolysed by water.
