WebCrystal field theory was developed by considering two compounds: manganese (II) oxide, MnO, and copper (I) chloride, CuCl. Octahedral Crystal Fields. Each Mn 2+ ion in manganese (II) oxide is surrounded by six O 2- ions arranged toward the corners of an octahedron, as shown in the figure below. MnO is therefore a model for an octahedral … WebApr 27, 2024 · C.F.T fails to explain the behaviour of certain metals which cause large splitting while others show small splitting. For example, the theory has no explanation as to why H 2 O is a stronger ligand as compared to OH –. So, these are some drawbacks of Crystal Field Theory.
WebNov 10, 2024 · The postulates of CFT Theory is mentioned below: The crystal field theory considers that the metal ion is situated in an electric field caused by the surrounding ligands.
