Nettet592 Points. The valence bond theory was fairly successful in explaining qualitatively the geometry and magnetic behaviour of the complexes. But, it could not explain the following : (i) The origin of their absorption spectra could not be explained. (ii) Why did different complexes of the same metal show different colours. NettetMolecular Orbital Theory (MOT): The VBT has two most serious limitations that electrons in molecules are treated as though they are localised and behave almost as they did in isolated atoms. This means that the VBT retains the individuality of the atoms composing molecule. The problem can be resolved by introducing the resonance theory, but ...
