The Diels-Alder reaction you will conduct in this experiment is between cyclopentadiene and maleic anhydride (the anhydride of cis-2-butendioic acid): diene dienophile The glassware is predried and a drying tube is used to prevent the hydrolysis of maleic anhydride to maleic acid (cis-2-butendioic acid): On heating, maleic acid isomerizes to fumaric acid (trans-2-butendioic acid). Show the mixture of products that would be formed if a small amount of moisture was present in the Diels-Alder reaction you have performed.
