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.
(b)

- For each proposed set of resonance structures: a. (E) Add curved arrows (starting from left) to show how each successive r.s. was generated. b. Cross out any resonance structures that are NOT important, and explain your reasoning.arrow_forwardDraw a reasonable resonance structure for the following species. Draw out all bonds to the oxygen atom in your answer.arrow_forwardPlease draw a more stable resonance structure for the following molecule. Use a curved arrow to show how to transform the original structure to the new one and please specify charges.arrow_forward
- Which of the following shows correct arrow placement that represents significant resonance for the given molecule? None of the choices given represent significant resonance. Save for Laterarrow_forwardDraw the major resonance structure for the compound shown; include lone pairs of electrons, formal charges, and condensed hydrogen atoms (located in the More menu). Then draw curved arrows to show how this can be converted to the Lewis structure givenarrow_forwardAdd the curved arrow(s) to each resonance structure that are necessary to convert it to the next structure. (The final resonance structure requires no curved arrows.)arrow_forward
- based on the photo, draw the correct curved arrow(s) that generate(s) the resonance structure:arrow_forwardFollow the curved arrows to draw a second resonance structure for eachspecies.arrow_forwardDraw the curved arrows to show the resonance structure for the following molecules. ( there are 3 molecules )arrow_forward
- The curved arrow notation is a powerful method used by organic chemists to show the movement of electrons not only in resonance structures, but also in chemical reactions. Since each curved arrow shows the movement of two electrons, following the curved arrows illustrates what bonds are broken and formed in a reaction. Consider the following reaction. Choose the correct image that shows the curved arrows to show the movement of electrons.arrow_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_forwardDraw all possible resonance forms for anisole using appropriate arrow notation. Which resonance structure is most stable? Which is least stable? Draw the resonance hybrid for anisole, indicating all partial charges.arrow_forward
