This looks correct to me! <3 have a good day
It is 0.5474 but you can put 0.5 hope this helps
Answer: cycloaddition of 1,3-butadiene and allyl anion is thermally allowed.
Explanation:
Using the frontier molecular orbital approach, we consider if the symmetry of the LUMO of the diene (1,3-cyclobutadiene) and the HOMO of the dienophile allyl anion), match each other since the diels alder reaction is a symmetry allowed process. The symmetries of these frontier molecular orbitals match each other hence the reaction is thermally allowed. It should be notes that 4+2 cycloadditions are thermally allowed although they are slow.
Im assuming that the 2 is a sub of the Al and not the # for O and that u made a type of AL which is Al
its been a while but
Al2O3 + 6HCl = 2ALCl3 + 3H2O
