1. a) Match the five complexes grven below (by letter) with the proper spectral data in the chart below. Al1 of these complexes have low spin d6 configurations and display t'*ro d-d transitions (low absorptivity). Two additional absorptions with high molar absorptivity are observed for the bromo complexes.
A. [Co(OH2)6]3+B [Rh(OH2)6]3+C [RhBr6]3-
D [Rh(NH3)6]3+E [rBr6]3-
b) what is the origin of the high absorptivity absorptions and why are they only observed for two of the complexes?
