Question

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

Answer 1

because of greater electonegativity there is a shift of electrons towards the atom reducing the bond pair - bond pair repulsion and inturn reducing the bond angle
so the decreasing order of electonegativity is
F, Cl, Br, I
so the order increasing bond angle is
NF3, NCl3, NBr3, NI3
tag me the brainliest

Answer 2

Answer:

NI3 < NBr 3 < NCl3 < NF3

Explanation:

it is because from top to bottom size increases Lone pair bond pair repulsion increases and the bond angle decreases. lone pair bond pair repulsion is greater than bond pair bond pair repulsion.

NI3 < NBr 3 < NCl3 < NF3
