Question
Give reason for the following:
$NCl_3$ gets readily hydrolysed while $NF_3$ does not.
✓

Answer

In $NCl_3,$ Cl has vacant d-orbitals to accept the lone pair of electrons donated by O-atom of $H_2O$ molecule but in $NF_3,\ F$ does not have d-orbitals.
$NCl_3 + 3H_2O → NH_3 + 3HOCl$
$NF_3 + H_2O →$ No reaction
