NEET Chemistry (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
A molecule of PCl5 is described as having a trigonal bipyramidal structure in gaseous and liquid phases. Which of the following statements is true regarding the bond lengths in PCl5?
A
The axial P-Cl bonds are longer due to greater repulsion.
B
All P-Cl bonds are of equal length.
C
The equatorial P-Cl bonds are longer due to lower repulsion.
D
The axial P-Cl bonds are shorter than the equatorial bonds.
Correct Answer
Option A
Detailed Explanation
In gaseous and liquid phases, PCl5 has a trigonal bipyramidal structure where the axial P-Cl bonds are longer than the equatorial bonds because the axial bond pairs suffer more repulsion.
