PCI_(5) is less stable. Why? – InterviewSolution

1.	PCI_(5) is less stable. Why?
Answer» SOLUTION :`PCI_(5)` molecule has trigonal bipyramidal structure. The three EQUITORIAL bonds are equivalent. The `P-Cl` bond length in equitorial POSITION is 202 pm. The twoaxial bonds (240 pm) are longer. The axial bonds suffer more repulsion as compared to theequatorial bonds. HENCE, `PCI_(5)` is less stable.
