Interpretation:
The given species is to be identified as aromatic, antiaromatic, or nonaromatic based on Huckel’s rules.
Concept introduction:
Aromaticity is not limited to uncharged molecules because several molecular ions that obey Huckel’s rules are also aromatic.
The rule for aromaticity or antiaromaticity applies only if the system is planar, cyclic and has overlap of p-orbitals. Huckel’s rule for aromaticity states that if a species possesses a pi system of molecular orbitals constructed from p-orbitals that are fully conjugated around a ring (
1) Aromatic if the number of electrons in that
The hybridization of the carbon atom bearing the positive charge is

- Explain 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_forwardCurved arrows are used to illustrate the flow of electrons. Use the reaction conditions provided and follow the curved arrows to draw the resonance hybrid contributor. Include all lone pairs and charges as appropriate..arrow_forwardKindly explain why COSe is the answer in detail.arrow_forward
- Curved arrows are used to illustrate the flow of electrons. Using the provided resonance structures, draw the curved electron-pushing arrows to show the interconversion between resonance hybrid contributors. Be sure to account for all bond-breaking and bond-making steps.arrow_forwardOrganic Chemistry problem. Please help solve. Provide reasonable product structure for reaction shown in the attached image. Thank you.arrow_forwardUsing the curved arrow formalism, draw two major resonance contributors to the structure of the following molecule. Circle that structure that contributes most to the overall structure.arrow_forward
