Give chemical reaction in support of the statement that all the bonds in `PCl` molecule are not equivalent.

Explanation

Due to greater bond pair-bond repulsions, the two axial P-Cl bonds are less stable than the three equatorial P-Cl bonds. It is because of this reason tht when `PCl_(5)` is heated, the less stable axial bonds are broken to form `PCl_(3)` and `Cl_(2)`.
`PCl_(5)overset(Delta)toPCl_(3)+Cl`
