Which of the following statements concerning octahedral coordination complexes is not correct? A) Strong field ligands produce large octahedral ligand field splittings. B) Weak field ligands produce high spin complexes. C) Halide ions are strong field ligands. D) Weak field ligands result in relatively small values for Δ_o. E) A relatively large value for Δ_o causes a complex ion to absorb relatively high energy (shorter wavelength)light.

Question

Quizplus · Accepted Answer

Halide ions are generally considered to be weak field ligands, not strong field ligands as stated in statement C. The other statements are correct. Strong field ligands result in large ligand field splittings and low spin complexes, while weak field ligands result in small ligand field splittings and high spin complexes. The magnitude of Δ_o determines the energy of light absorbed, with larger values resulting in absorption of higher energy (shorter wavelength) light.
