Concept explainers
Interpretation:
Whether the given compound will have a significant dipole moment is to be determined. If so, the direction of the dipole moment is to be determined.
Concept introduction:
If two rings are with conjugated double bonds and are joined by a double bond, it is possible that one or both may achieve
The resulting charge separation will make the molecule polar. Additionally, the delocalization of the charge due to the aromatic character of the ring(s) will increase the separation between charges, giving the molecule a substantial dipole moment.
The direction of a molecular dipole is from the atom or region with a positive charge toward the atom or region with a negative charge.

- Consider the following bases: a. For each base above, circle the atom/atoms with the highest PE (will release the most P.E.when a lone pair on this atom combines with an H+ ) b. Rank the bases 1 (highest P.E./strongest base) to 7 (lowest PE/weakest base), and explainyour reasoning.arrow_forwardWhich hydrogen in each molecule is most acidic? (See the Attachment)arrow_forwardCurrent Attempt in Progress For the given cation, draw all significant resonance forms and rank them from most significant to least significant. Briefly explain the rankings. Part 1 Ⓒ H Because this is a charged species, let's focus on resonance patterns that can delocalize the charge. First, add curved arrow(s) to show the resonance using the following pattern: a lone pair next to a carbocation. 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.

- Question (Organic Chemistry) Consider molecules A–B. Does the arrow pushing in each structure leadto an acceptable resonance form? If so, explain why it is acceptable or unacceptable? What are the rules and logic? If so, draw it and carefully explain your answer and provide explanations for why each structure leds to an acceptable or unacceptable resonance form. Why is the arrow pushing acceptable or unacceptable in each individual case?
