Chapter 10, Problem 112IAE

In certain polar solvents, PCI, undergoes an ionization reaction in which a Cl- ion leaves one PCI, molecule and attaches itself to another. The products of the ionization are $PC{I}_4{}^{+}$ and $PC{I}_5{}^{-}.$ Draw a sketch showing the changes in geometric shapes that occur in this ionization (that is, give the shapes of $PC{I}_5{}^{-},PC{I}_4{}^{-}$ , and ${\text{PCl}}_{\text{6}}^{\text{-}}$ ).
$2PC{I}_5\rightleftarrows PC{I}_4{}^{+}+PC{I}_5{}^{-}$
