Question

Quizplus · Accepted Answer

(i) Ligand field theory is indeed based on molecular orbital theory, as it considers the metal-ligand bonds in terms of molecular orbitals formed from the metal d orbitals and the ligand orbitals. (ii) Ligand field theory can explain the spectrochemical series by describing how different ligands affect the energy gap between the d orbitals, which in turn affects the color and intensity of absorption in the visible region. (iii) is incorrect because ligand field theory does take into account the s and p atomic orbitals on the metal, especially when considering high-spin and low-spin configurations in octahedral complexes.
