Concept explainers
Interpretation:
The structure of the reactive species formed in the reaction
Concept introduction:
Most of the organic structures cannot be represented using a single Lewis structure. Therefore, there exists more than one Lewis structure for representing a molecule or ion. These structures are known as resonance structures. The delocalization of electrons results in the formation of resonance structure. The curved-arrow notation traces the flow of the electrons in a compound. This notation is used to derive the resonance structure.

- Compare Electrophilic aromatic substitution reactivity to quinoline and isoquinoline. Please, explain with diagramsarrow_forwardGive a clear handwritten answer of this reactionarrow_forwardGive the structure(s) of the product(s) of each reaction. Indicate any relative stereochemistry, assuming that each of the Diels-Alder reactions will proceed with endo selectivity. If more than one product is formed, please indicate which one will be the major product or if they will be formed in equal amounts. If no reaction is expected to occur under the indicated conditions, then write "no reaction" or NR, and explain why you would expect nothing to occur. In all cases, equimolar amounts of both components/reagents are present unless indicated otherwise.arrow_forward
- Pyridazine and Pyridine represented by two chemically identical resonance structures, however, the same is not true for pyridazine. Provide a rational for the favored isomer.arrow_forwardTaking into account for resonance, which compound would not be a possible product of this reaction? Or are all of them possible products?arrow_forwardRank the following compounds according to their reactivity to HCN and justify whyarrow_forward
- Using the Frost Circle method to outline the molecular orbitals of cyclobutadiene. and identify whether it is aromatic, antiaromatic or non-aromatic. Explain. (Note: Show the outline of MO of cyclobutadiene using the Frost circle method)arrow_forwardhow to distinguish this two HNMR , first one is belonge to DIELS Aldere adduct and second NMR is for dicarboxylic acid which is the final product.arrow_forwardWhich of the following compounds can arise directly from a Diels-Alder reaction? Circle any structures that can. Then, identify the appropriate diene(s) and dienophile(s) that would lead to the compound. Pay attention to E-/Z- stereochemistry in all of the reactants. For those that cannot undergo a Diels-Alder reaction, please explain why.arrow_forward
