Based on the energies you found in c and d, which of these complexes has the largest predicted splitting between the t2g orbitals and the eg orbital. Remember--not every element has occupied d-orbitals. How is that going to impact your next answers?
Which one would absorb the longer wavelength of light? Explain why.
Transition metal complexes are often vibrantly colored due to the splitting of the d-orbitals caused by the ligands. Based on your results would you expect that both of these complexes have any significant color? Explain.
