Concept explainers
Interpretation:
Out of the two shown structures, the resonance structure that makes a greater contribution to the resonance hybrid is to be determined.
Concept introduction:
Resonance structures are alternate Lewis structures that can be drawn for a molecule. All the resonance structures do not contribute equally to the resonance hybrid. The structure with the lowest energy contributes the most. A greater number of atoms (other than hydrogen) with an octet of electrons and a greater number of covalent bonds results in a lower energy structure. A lower number of atoms with formal charges also leads to a lower energy structure.
Formal charge (FC) on an atom is calculated as
