Both C CI_4 and SiCI_4 has stable octets of the central atoms, but SiC

1.	Both C CI_4 and SiCI_4 has stable octets of the central atoms, but SiCl_4, is acidic. Why?
Answer» Solution :`C CI_4` is saturated. The central atom carbon has no VACANT d-orbitals in its valence SHELL. `SiCl_4` is a Lewis ACID. The central atom silicon has empty d-orbitals in the VALENCY shell and excitation is easy. It ACTS as Lewis acid, by expanding its octet configuration.
