Question

are all the five bonds in Pcl5 molecule equivalent​

Answer 1

Answer:

No

Explanation:

In PCl5, phosphorous is in sp3d hybridized state but all its five bonds are not equivalent.

In gaseous and liquid state, PCl5 has a trigonal bipyramidal structure. In this structure, the two axial P-Cl bonds are longer and less stable than the three equatorial P-Cl bonds. This is because of the greater bond pair - bond pair repulsion in the axial bonds. Hence, all the bonds in PCl5 are not equivalent.
