In certain polar solvents, PCl 5 undergoes an ionization reaction in which a Cl - ion leaves

Question:

In certain polar solvents, PCl₅ undergoes an ionization reaction in which a Cl^- ion leaves one PCl₅ molecule and attaches itself to another. The products of the ionization are PCl₄⁺ and PCl₆^-. Draw a sketch showing the changes in geometric shapes that occur in this ionization (that is, give the shapes of PCl₅, PCl₄⁺, and PCl₆^-).
