Question

The hydrolysis of ${NF}_3$ does not takes place where as hydrolysis of ${NBr}_3,{NI}_3,{NCI}_3$ takes place:

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

Answer 1

The correct option is A because of high polar character of ${NF}_3$

Hydrolysis of $N{F}_3$ doesn't take place because back bonding takes place here($F$ is electronegative).

Strong polar bond prevents it from further reactions.

So, high high polar character of $N{F}_3$ doesn't let hydrolysis take place.
