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.

Lo What is an appropriate resonance structure of the ion? Select one: H-C - :0:arrow_forward
- Nhy is resonance structure A and resonance structure B not the same structure? If you rotate the molecule like a spicket handle (l. e. clockwise with the C at the center and the R group remaining in place as you look down the C - R bond) wouldn't you get the same thing? Why are these not equivalent structures? Resonance structure A t Resonance structure B Actual structurearrow_forwardwhich of the pair is more stable, resonance structure if neededarrow_forwardWhich of the following species is a valid resonance structure of A? Usecurved arrows to show how A is converted to any valid resonancestructure. When a compound is not a valid resonance structure of A,explain why not.arrow_forward
- When 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.
