1. H NMR Spectra of the Diels -Alder Adduct from anthracene and maleic anhydride (The maleic anhydride is slightly water sensitive). Weigh out 0.80g of anthracene and 0.40g of maleic anhydride (both are solids). Add the two solids into the flask. (Be sure the flask has cooled for at least two minutes before adding the solids, or they will melt.) Carry the round-bottomed flask to the hood Compare and contrast the IR spectra of your starting materials (anthracene and maleic anhydride) and product (9,10-dihydroanthracene-9,10-a,b-succinic anhydride) and explain how the IR data for the product confirms the formation of the Diels-Alder adduct. Pay special attention to … Xylene (6 mL), anthracene (0.5 g), and maleic anhydride (0.25 g) were added to a round bottom flask (25 mL). The solution turned a yellow color when the reactants were added together.
