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.

- 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_forwardThe following structure is an anion with three possible resonance contributors. One incomplete resonance form is shown below. Complete the given structure by adding nonbonding electrons and formal charges. Draw the two remaining resonance structures (in any order), including nonbonding electrons and formal charges.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_forward
- Draw 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_forwardDraw all reasonable resonance structures for the following cation. Then draw the resonance hybrid.arrow_forwardDraw the other resonance structures that can be generated from the one shown below. Identify the resonance structure that resembles the hybrid the most.arrow_forward
- Draw an arrow pushing pattern represents the flow of electrons that converts the first resonance structure into the second resonance structure?arrow_forwardDraw the correct curved arrow that generates the resonance structure shown.arrow_forwardDraw all reasonable resonance structures for the following cation. Thendraw the resonance hybrid.arrow_forward
- For the given compound, draw all significant resonance forms and rank them from most significant to least significant. Briefly explain the rankings. Part 1 Let's begin by considering which resonance patterns are present. First, add curved arrow(s) to show the resonance using the following pattern: a pi bond between two atoms of differing electronegativity. Modify the second structure given to draw the new resonance structure. Include relevant formal charges in your structure. Use the + and - tools to add/remove charges to an atom, and use the single bond tool to add/remove double bonds.

Include relevant formal charges in your structure. Use the + and - tools to add/remove charges to an atom, and use the single bond tool to add/remove double bonds.arrow_forwardDraw the best Lewis structure for HCN and determine the formal charge on the nitrogen. Please just put in single number for answer. If it is positive no need for the +, if it is negative, please use the -.arrow_forward
