NEET Chemistry (general) MCQ Question
Type: MCQ-numerical-Hard-Class 12
Based on the VSEPR theory, what is the molecular geometry of BrF3 and why do the lone pairs occupy equatorial positions in its structure?
A
T-shaped; to minimize lone pair-lone pair repulsions
B
Trigonal planar; to minimize bond pair-bond pair repulsions
C
Linear; to maximize bond angles
D
Square planar; to stabilize the molecule
Correct Answer
Option A
Detailed Explanation
BrF3 has a T-shaped geometry because it has three bond pairs and two lone pairs. The lone pairs occupy equatorial positions to minimize the lone pair-lone pair and bond pair-lone pair repulsions, which are greater than bond pair-bond pair repulsions.
