Concept explainers
Interpretation: The major focus of the crystal field model, the splitting of d orbitals into two sets for an octahedral complex and the two sets of orbitals are to be stated. Also the definition of weak-field ligand, strong-field ligand, low-spin complex and high-spin complex are to be defined. The magnetic behavior of the given complexes and whether they have the same d-orbital splitting diagram are to be explained.
Concept introduction: Crystal field theory states the breaking of degenerate orbitals (d or f orbitals) because of the presence of static electric field which is produced by the charge distribution of the neighboring anions. The octahedral complexes are those in which six atoms or ligands are arranged symmetrically around a central metal atom. Paramagnetic complexes are attracted towards the magnetic field and contain unpaired electron whereas diamagnetic complexes have all the electrons paired and hence, repelled from the magnetic field.
