Resonance concept for dealing benzene and carbonate ion species has to be explained along with the molecular orbitals of these sepcies. Concept Introduction: Resonance concept is used to describe delocalized electrons within molecules or polyatomic ions. When Lewis structure cannot describe the entire bonding that takes place in a molecule, resonance structures are used. The structures that arise due to delocalization of electrons or charges is called as resonance structures or canonical structures. If a species can be represented in resonance structures, the pi bonds of the species are delocalized. Molecular orbitals are formed by the combination of the atomic orbitals of the atoms in the molecule. The properties of the newly formed molecular orbital will be different from their individual atomic orbitals. In molecular orbital theory, electrons shared by atoms in a molecule reside in the molecular orbitals. Delocalized molecular orbitals are extended over two or more atoms, these are not confined to adjacent bonding atoms. Therefore, the electrons are free to move around the entire molecule.
