You are comparing two coordination complexes that have the same molecular shape and central metal cation. Complex A has only chloride ligands and Complex B had only CO ligands. Which statements are true regarding the complexes? Select all that apply. Complex A has the smaller crystal field splitting. Light of higher frequency is required to promote an electron from the lower to the higher d orbitals in complex A relative to complex B. The light emitted as a photon is released to relax an electron from higher to lower energy d orbitals has a longer wavelength for complex A. Light of higher frequency is required to promote an electron from the lower to the higher d orbitals in complex B relative to complex A. The light emitted as a photon is released to relax an electron from higher to lower energy d orbitals has a longer wavelength for complex B. Complex B has the smaller crystal field splitting.
