Your next bonus is visual. Shown in the image are three d-metal splitting energy diagrams, labeled A, B and C, as well as the complexes platinum (II) tetrachloride, nickel tetracarbonyl, and cobalt (III) hexaamine, labeled 1, 2, and 3, respectively. Note that the energy splittings in the image are not necessarily to scale. Answer the following two questions using this image: 1) By letter and number, pair each complex to its corresponding splitting diagram 2) By number, which of the three complexes are predicted to be diamagnetic?
