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.

When a compound is not a valid resonance structure of A,explain why not.arrow_forwardWhen drawing a resonance hybrid, how is the relative significance of individual resonance structures represented? O The entire resonance structure will be drawn larger or smaller, depending on its significance. O There is no way to note the significance of a resonance structure in atdrawing. The most significant resonance structure is circled. The partial charges will be written larger or smaller, depending on the significance of the resonance structure.
