Question

which of the following halides can not be hydrolysed A.NCl3 B.NF3 C.PCl3 D.BiCl3​

Answer 1

NF3 can not be hydrolyzed.

Option (B) is correct.

Explanation:

• Hydrolysis means the breakdown of water and it occurs through the coordination of lone pair of electrons of water.
• In NF3 the d-orbitals of both fluorine and nitrogen are completely filled and it can not accept the lone pair.
• SF6 strongly repels the incoming molecules of water and has zero dipole moment.
• TeF6 has also octahedral geometry and zero dipole moment.
