Can you also go into detail about drawing the HOMO and LUMO,
like how to know how many molecular orbitals there should be and
how many orbitals I should draw? Thanks!

Consider the Diels-Alder cycloaddition reaction below and complete parts (a)-(b) below. D = deuterium = 2H (a) Draw the major regioisomer (or in other words, constitutional isomer) expected to form. Also, draw appropriate resonance structures to explain why only one constitutional isomer is expected to form. Discuss the interactions between the diene and dienophile that govern this constitutional isomer being the only one expected. (b) Redraw the regioisomer from part (a) and show the appropriate stereochemistry using correct dash/wedge notation expected for the...
