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.
