Of the following assertions regarding the mechanism of electron transfer: A. An outer-sphere mechanism involves electron transfer from the reductant to the oxidant, with the coordination shells or spheres of each staying intact. B. In the inner-sphere mechanism, the reductant and oxidant share a ligand in their inner or primary coordination sphere which assists in electrons being transferred. C. In the inner-sphere mechanism, an oxidant possesses at least one ligand capable of binding simultaneously to two metal ions. D. In the inner-sphere mechanism, ligands of reductant are substitutionally inert. The correct statements are:
