Question:

Henry Taube, the 1983 Nobel Prize winner in chemistry, has studied the mechanisms of oxidation-reduction reac¬tions involving transition metal complexes. In one experi¬ment he and his students studied the following reaction:

Qiromium(IO) and cobalt(III) complexes are substitutionally inert (no exchange of ligands) under conditions of the experiment. However, chromium(II) and cobalt(II) com-plexes can exchange ligands very rapidly. One of the products of the reaction is Cr(H2O)5CI2+. Is this consistent with the reaction proceeding through formation of (H2O)5Cr€”Cl€”Co(NH3)5 as an intermediate? Explain your answer.
