Concept explainers
(a)
Interpretation:
The given pairs of structures should be identified that whether they are resonance contributors or different compounds.
Concept Introduction:
Resonance Contributor: The appropriate structure with the localized electrons is called a resonance contributor, a resonance structure, or a contributing resonance structure.
Delocalized electrons: The sharing of electrons between two or more atoms known as delocalization of electrons. In order to have delocalized electrons, the system must be planar and have alternative double bonds and single bonds.
Resonance hybrid: The actual structure with delocalized electrons is called a resonance hybrid.
(b)
Interpretation:
The given pairs of structures should be identified that whether they are resonance contributors or different compounds.
