Give chemical reaction in support of the statement that all the bonds in PCI_(5) molecule are not equivalent.

Answer»

Solution :Due to GREATER BOND pair-bond pair repulsions, the TWO axial P-CI bonds are less stable than the three equatorial P-CI bonds. It is because of this reason that when `PCI_(5)` is heated, the less stable axial bonds are broken to form `PCI_(3) and CI_(2)`
`PCI_(5) overset(Delta) rarr PCI_(3) + CI_(2)`
