Interpretation:
Based on the characteristics of the MO diagram of cyclobutadienyl dication, it is to be determined if it is aromatic, antiaromatic, or nonaromatic.
Concept introduction:
To derive the relative energies of pi molecular orbitals, a Frost method is used. This method is applicable to any species with a fully conjugated, cyclic pi system. This method involves drawing a polygon that represents the cyclic compound’s line structure, with one of the vertices pointing directly upwards. Each of the four vertices then represents the energy of a
Antiaromatic compounds have cyclic
Nonaromatic compounds are neither unusually stable nor unusually unstable.

- Although the hypothetical molecule shown here has alternating single and double bonds, those double bonds are not considered to be conjugated. Why not?arrow_forwardCan i have simple explanation also why the answe should be like that ? Thank you ?arrow_forwardTo practice types of aromatic reactions, this next practice problem provided us these reactions. What are the products?arrow_forward
- Why is there no coupling between the a and c protons or between the b and c protons in the cis and trans alkenes shown in Figurearrow_forwardBased on your answer to below Problem, do you thinkthe compound shown here should have a significantdipole moment? If so, in which direction does it point? The molecule shown here has quite a large dipole, asindicated in its electrostatic potential map. Explain why.Hint: Consider various resonance structures.arrow_forwardOn the following given which is/are meso compound(s)?arrow_forward
- Please highlight the structure in colors so I can understand clearly. Thanksarrow_forwardshouldn't a hydride shift take place for the HI and the tH20, H+ reactions in order to get the major product. Also please draw the enantiomers and diastereomers products (if there are any) and if there aren't explain why for all the reactionsarrow_forwardShow the curved arrow formalism in order to arrive in the major final productarrow_forward
