In `PCl_(5)` phosphorus is in `sp^(3)` d hybridised state but all its five bonds are not equivalent. Justify your answer with reason.

Text Solution

Verified by Experts

It has trigonal bipyramidal geometry, in which two Cl atoms occupy axial position while three occupy equatorial positions . All five P__Cl bonds are not identical. There are two types of bond lengths ("i) Axial bond lengths (ii) Equatorial bond lengths

Thus, difference in bond length is due to fact that axial bond pairs suffer more repulsion as compared to equatorial bond pairfs.

All bonds in the molecule of PCl_(5) are not equivalent. Explain.

The hybrid states of phosphorous atoms in each PCl_(5) and PBr_(5) in gasesous phase are sp^(3)d . But, in solid PCl_(5) ,phosphorous shows sp^(3)d^(2) and sp^(3) hybrid states. While,P in PBr_(5) is in sp^(3) hybrid state. This is because:

All five bonds of PCl_(5) are not equilvalent and PCl_(5) is less stable. Explain.

Explain the structure of PCl_(5) according to hybridization. Why all P – Cl bonds lengths are not equivalent in PCl_(5) ?
