NEET Chemistry (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 12
In the gaseous and liquid phases, phosphorus pentachloride (PCl5) exhibits a trigonal bipyramidal structure. Which of the following statements about the bond lengths in PCl5 is correct?
A
The axial P–Cl bonds are longer than the equatorial bonds.
B
All P–Cl bonds are of equal length.
C
The equatorial P–Cl bonds are longer than the axial bonds.
D
The axial and equatorial P–Cl bonds have the same length in the solid state.
Correct Answer
Option A
Detailed Explanation
In gaseous and liquid phases, PCl5 has a trigonal bipyramidal structure with axial P–Cl bonds being longer than the equatorial bonds due to increased repulsion experienced by axial bond pairs.
