Question

The hydrolysis of $N{F}_3$ doesn't takes place where as hydrolysis of $NB{r}_3$, $N{I}_3$ and $NC{l}_3$ takes place.

• A. because of high polar character of $N{F}_3$
• B. because of less polar character of $N{F}_3$
• C. because of absence I.p of electrons in $N{F}_3$
• D. because of absence of vacant d-orbitals in N & F.

Answer 1

Answer: (D)

because of absence of vacant d-orbitals in N & F.

As flourine and nitrogen both are most electronegative and small in size.

So they are tightly packed that's why they don't go undergo hydrolysis.

There is another reason, both don't have vacant d-orbital and hydrolysis occur with coordination bond with water.
Option D is correct.
