NEET Chemistry (general) MCQ Question
Type: MCQ-numerical-Hard-Class 12
In the gaseous phase, phosphorus pentachloride (PCl5) exhibits a trigonal bipyramidal structure. If the bond length of equatorial P-Cl bonds is 202 pm, what is the expected length of the axial P-Cl bonds?
A
214 pm
B
202 pm
C
222 pm
D
190 pm
Correct Answer
Option C
Detailed Explanation
The NCERT context explains that the axial bonds in PCl5 are longer than the equatorial bonds due to more repulsion experienced by the axial bond pairs. Therefore, the axial bond length would be expected to be greater than the equatorial bond length of 202 pm.
