Question

CCl4 does not undergo hydrolysis but SiCl4 undergoes hydrolysis. Why?

Answer 1

hey❤

here is ur answer!!

Reason :

The inability of CCl4 to undergo hydrolysis is due to the absence of vacant d orbitals in the valence shell of carbon. Due to this the carbon atom in CCl4 is unable to expand its octet and thus it does not undergo hydrolysis.

On the other hand silicon atom possesses vacant d orbitals in its valence shell and can utilise them for accommodating electron pairs given by water molecules.

Thus Silicon in SiCl4 can expand its octet as result undergoes hydrolysis.

hope it helps!!

thanks☺

Answer 2

Absence of d-orbital
