(a) `BF_(3) and BrF_(3)` molecule has different shapes. Expain.
(b). `C Cl_(4)` cannot be hydrolysed but `SiCl_(4)` can be, why?

Text Solution

Verified by Experts

(a).
(b) C does not have vacant d-orbital for expansion of octet.
`SiCl_(4)+4H_(2)O to Si(OH)_(4)+4HCl`
Due to availabiity of vacant d-orbitals in valence shell of their central atom, they can easily extend teir coordination number beyond four but this is not possible in case of carbon due to absence of vacant d-orbital.
