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

- Draw the resonance contributors for the species/molecules shown in the boxes below. Then, indicate which species (if any) is the MAJOR contributor towards the resonance hybrid (most stable).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_forwardConsider 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_forward
- Which of the following resonance structures has the greatest contribution to the hybrid? Explain.arrow_forwardShown on the left is a cationic intermediate for the electrophilic addition of chlorine to the para position of phenol. Draw the resonance stucture that is the major contributor. Include all nonbonding electrons.arrow_forwardFuran, shown below, exhibit resonance stabilization. Which of the following is an INVALID resonance structure of furan?arrow_forward
- Please give me idea why resonance is more reactive. I thought If resonance exists, it delocalizes more, and means less reactivearrow_forwardUse Huckel’s rule to identify if its aromatic or not. Draw the resonance structure of the ff. compounds. note: I need the answer immediately. I will send a good rate right away as well.arrow_forward! ( give answer with detail explanation which option correct and why , which option wrong and why)arrow_forward
- I understand where the proton transfer occurs but not what the products will look like. Can you draw curved arrows to show proton transfer and what the reaction products would look like? And explain which side is favored and whyarrow_forwardMay you explain and answer this one pleasearrow_forwardPlease explain which resonance contributor would be the best and why.arrow_forward
