Vedclass · Answer

(B) The tetrahalides of group $14$ elements are covalent and possess a tetrahedral geometry.Except for carbon,all other group $14$ tetrahalides $(MX_4)$ have vacant $d$-orbitals in the central atom.These vacant $d$-orbitals allow the central atom to accept electron pairs from donor molecules,thereby acting as $Lewis$ acids.Carbon lacks vacant $d$-orbitals and cannot expand its octet,thus it does not act as a $Lewis$ acid.
