Question 2. Consider the Diels-Alder reaction below. (15 pts total) 2a. Determine the product and include a mechanism. Would you expect to see the endo-, exo-, or endo-lexo- adduct as the major product for this reaction and why? (Hint: stereochemistry is typically retained from reactant to product. (5 pts) 2b. The major isomer above was purified and collected. Use the NMR provided (filename: Lab6_Q2b) to verify if the reaction was successful or not. Label distinct peaks. Include an integrated NMR for credit (printed copy or screenshot or MNova file). (10 pts) In DMSO-d6
