Quizplus · Accepted Answer

The diene needed for this synthesis is 1,3-butadiene (I) and the dienophile needed is maleic anhydride (II). The product is a Diels-Alder adduct, which can be formed by heating the diene and dienophile together under appropriate conditions. Choice B shows 1,3-butadiene and maleic anhydride as the reactants, indicating that this is the correct choice for the synthesis.
