Which statements are true regarding ligands? Select all that apply. Ligands donate all electrons involved in bonds they form with metal cations. Ligands are electron pair acceptors in coordination complexes. Ligands act as Lewis bases in coordination complexes. Ligands form ionic bonds with transition metals. All ligands with two lone pairs are bidentate. A ligand that can donate more than one electron pair to a metal cation is called a chelate. One ligand can donate only one lone pair to a metal cation.

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.
