Diels-Alder Reactions Regiochemistry and Molecular Orbital Theory for Cycloadditions

The video provides a discussion on the regiochemical outcomes of Diels-Alder reactions and describes cycloaddition reactions using molecular orbital theory.1 By the end of the video, viewers should be able to: – Understand what affects the regioselectivity of Diels-Alder reactions and predict the outcomes. – Describe cycloaddition reactions using molecular orbitals. – Determine whether a cycloaddition reaction is symmetry-allowed or symmetry-forbidden under thermal or photochemical conditions.
