Consider the Possible Thermal [4+4] Cycloaddition of Two Molecules of 1,3-Butadiene

question 2

Essay

Consider the possible thermal [4+4] cycloaddition of two molecules of 1,3-butadiene to generate cycloocta-1,5-diene. Show the HOMO/LUMO interaction which would result, and use this interaction to predict whether the proposed cycloaddition could occur.
