In \[Br{{F}_{3}}\] molecule the lone pairs occupy equatorial position to minimize:

A) Lone pair - bond pair repulsion only

B) Bond pair - bond pair repulsion only

C) Lone pair - lone pair repulsion and lone pair bond pair repulsion

D) Lone pair - lone pair repulsion only

Correct Answer: D

Solution :

[d] Lone pair-lone pair repulsion only \[Br{{F}_{3}}\]molecule In this molecule lone pair decide the shape. It has two lone pairs and three bond pairs based on Ip-lp, Ip-bp and bp-bp repulsion it is found that it has least repulsion.
