For number 4, the given was "Combine 2.5 g of butadiene sulfone, 1.2 g of finely ground maleic anhydride, and 0.80 mL of xylene to a 50-mL round-bottom flask. Be sure to write the exact mass of your reagents in your notebook. Add a magnetic stirbar."

4. Determine the theoretical yield of product, in both mmol and grams. Assume you start with the amounts indicated in the experimental handout. Show all work. 5. Why would adding concentrated H2SO4 in the last step of the reaction help the crystallization process if solid product does not initially appear? 6. Predict the relative rates for the reaction of 1,3-butadiene with the dienophiles below (1=fastest, 3=slowest). 4. Determine the theoretical yield of product, in both mmol and grams.
