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

Text Solution

Verified by Experts

Both nitrogen and fluorine atoms do not have any vacant `d-`orbitals to accept electron pairs from the oxygen 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`
