Concept explainers
(a)
Interpretation:
To supply necessary curved arrow(s) to convert the resonance structure on the left into the one on the right.
Concept introduction:
In the two species, the bonds are delocalized. This delocalization of bonds in species can be explained using resonance concept. Resonance exists in species for which there are two or more valid Lewis structures. For such species, each valid Lewis structure is called a resonance structure or a resonance contributor. The delocalization is shown using curved arrows.
