Question 11A.28: NCl3 is readily hydrolysed while NF3 does not. Explain....

In NCl_3, Cl has vacant d-orbitals to accept the lone pair of electrons donated by oxygen atom of H_2O molecules. But in NF_3, F does not have vacant d-orbitals. Therefore, NCl_3 undergoes hydrolysis but NF_3 does not.

NCl _3+3 H _2 O \longrightarrow NH _3+3 HOCl

NF _3+ H _2 O \longrightarrow \text { No reaction }
