(iv) It does not give a quantitative interpretation of the thermodynamic
or kinetic stabilities of coordination compounds (v) It does not make exact predictions regarding the tetrahedral and
square planar structures of 4-coordinate complexes (vi) It does not distinguish between weak and strong ligands The crystal field theory (CFT) is an electrostatic model which considers
the metal-ligand bond to be ionic arising purely from electrostatic
interactions between the metal ion and the ligand
