Question

Arrange the following species in increasing order of bond angle:
NF3, NCl3, NBr3, NI3

Answer 1

NF3 < NCl3 < NBr3 < NI3.

Answer 2

Heyy

Explanation:

Since central atom is N in all cases, then bond angle increases with decreases in electronegativity of surrounding atoms.

Since order of electronegativity is F > Cl > Br > I

Hence, increasing order of bond angle is NF3 < NCl3< NBr3 < NI3
