`NF_(3)` is not hydrolysed while `NCl_(3)` can be readily hydrolysed. Explain.

Answer» Both nitrogen and fluorine atoms donot have any vacant d-orbitals to accept electron pairs from the oygen atom in `H_(2)O` molecule. Therefore, `NF_(3)` cannot be hydrolysed. However, `NCl_(3)` has vacant d-orbitals on chlorine atoms which can take up electron pairs from `H_(2)O` molecules. As a result, `NCl_(3)` can be hydrolysed.
`NCl_(3)+2H_(2)O to NH_(3)+3HClO`
