$NF_3$

Vedclass · Answer

(C) The stability of nitrogen trihalides towards hydrolysis depends on the presence of vacant $d$-orbitals on the central atom and the electronegativity of the halogen atom.$NF_3$ is the only nitrogen trihalide that is stable and does not undergo hydrolysis by water.This is because nitrogen does not have vacant $d$-orbitals to accept the lone pair of electrons from water,and the $N-F$ bond is very strong due to high electronegativity of fluorine,making the attack of water molecules difficult.In contrast,other nitrogen trihalides like $NCl_3$,$NBr_3$,and $NI_3$ undergo hydrolysis because the larger halogen atoms can facilitate the reaction or have lower bond energies.
