Explain why SiCl4 reacts with H2O but CCl4 does not?

Answer Posted / ajay swargiary

Si halides have vacant d-orbitals and can extend their co-ordination number beyond four. So it can undergo hydrolysis.
Sicl4 +H20 - -》 4HCl + SiCl4
Whereas Carbon halides are saturated compounds . Since carbon atoms has no d-orbital , it cannot increase its co-ordination number.
Hence carbon halides (CCl4) are not hydrolysed with water.
