Draw the major diene & dienophile reactants which would give the Diels-Alder adducts shown below. Draw each reactant (diene & dienophile) separately, and evaluate that answer before continuing.
To draw a formula use the Drawing Window on the left below Do not draw hydrogen atoms, and do not specify stereochemical configuration. When you are finished, check your answer by pressing the Check Diene/Dienophile button. A help screen is available for the drawing window.
