Chemical Bonding And Molecular Structure Question 431
In $ BrF_3 $ molecule,the lone pairs occupy equatorial positions to minimize repulsions [CBSE PMT 2004]
Options:
A) Lone pair– lone pair repulsion and lone pair–bond pair repulsion
B) Lone pair–lone pair repulsion only
C) Lone pair-bond pair repulsion only
D) Bond pair-bond pair repulsion only
Show Answer
Answer:
Correct Answer: B
Solution:
Bent T-shaped geometry in which both lone pairs occupy the equatorial position of the trigonal bipyramidal here $ (l_{p}-l_{p}) $ repulsion = 0 $ (l_{p}-b_{p}) $ repulsion = 4 and $ (b_{p}-b_{p}) $ repulsion =2
