diels alder reaction
Draw a structure for the exo product formed by cyclopentadiene and maleic anhydride. Because the exo form is more stable than the endo form, why is the endo product formed almost exclusively in this reaction? In addition to the main product, what are two side reactions that could occur in this experiment? The infrared spectrum of the adduct is given in this experiment. Interpret the principal peaks.
