Chemical Bonding And Molecular Structure Question 537
Question: In $ BrF_3 $ molecule,the lone pairs occupy equatorial positions to minimize [CBSE PMT 2004]
Options:
A) Lone pair- lone pair repuilsion 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
