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.

- With explanationarrow_forwardWhich of the following resonance structure for OCN- will contribute most to the correct structure of OCN-? O = C-N, with one lone pair on O and three lone pairs on N O=C=N, with two lone pairs on O, and two lone pairs on N O=C=N, with one lone pair on O, two lone pairs on C, and one lone pair on N O-C = N, with three lone pairs on O and one lone pair on N They All contribute equally to the structure on OCN-arrow_forwardThe bond energy (in kcal mol–1) of a C—C single bond is approximately?arrow_forward
- Consider the structure of the given ion. Lo What is an appropriate resonance structure of the ion? Select one: H-C - :0:arrow_forwardWhich structure represents a correct resonance structure for the following structure? Select one:arrow_forwardNhy 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_forward
- which of the pair is more stable, resonance structure if neededarrow_forwardUse bond energies listed in Table available on Canvas to find AHx for the reactions shown below: 1) Η H H H 1 H-0-0-H H-O-C-C- H CH₂O H + H CHÍNH H₂O NH₁ HICIH -O-Harrow_forwardWhich of the following species is a valid resonance structure of A? Use curved arrows to show how A is converted to any valid resonance structure. When a compound is not a valid resonance structure of A, explain why not.arrow_forward
