Concept explainers
Interpretation:
The possible resonance structures are to be drawn for the given ion, and the greatest resonance contributor is to be identified.
Concept introduction:
Resonance structures are alternate Lewis structures that can be drawn for a molecule or an ion. The overall charge on all the resonance forms must be the same. The contribution of all the resonance structures, to the resonance hybrid, is not equal. The lowest energy (more stable) resonance structure is the greatest resonance contributor to the hybrid. The stability of the resonance structure is governed by the following factors: greater number of atoms with octets, greater number of covalent bonds, and least number of formal charges. The order of stability of carbocation is

- 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_forwardExplain why the following reaction takes place as shown. Be sure to fully explain why the reaction sites are used and what is happening to the formal charges. Include a possible explanation for the negatively charged oxygen reacting with the carbon bonded to the Cl rather than the carbon bonded to the SH.arrow_forwardPlease help would and explain problemarrow_forward

For each structure of conjugate base draw all possible resonance structuresand finally rank all 3 C-H bonds in order of increasing their acidity.arrow_forwardUse curved arrow notation to show how the rst resonance structure can be converted to the second.arrow_forward
- Question (Organic Chemistry) Consider molecules A–D. 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? Explain you answer with many details, logic, and in a step-by-step fashion.arrow_forwardplease answer ASAP (provide an explaination too please)??arrow_forwardQuestion (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? Explain you answer with many details, logic, and in a step-by-step fashion. Please explain your rationale or logic.

- So, in this lewis acid-base reaction, do we need to draw lone pairs or not? Why or why not? Thank you.arrow_forwardThe molecule shown here has quite a large dipole, as indicated in its electrostatic potential map.
