answer: ideal bonding model would be the one to simplicity of the localized electrons model but with the delocalization characteristics of the molecular orbital model. This is achieved by combing the two models to describe molecules that require resonance. In case of Benzene and O3, the double bond that show charges in positions in the resonance structure. Since the double bond involves one ? and one? Bond, there is a ? bond between all bound atoms in each resonance structure....
