The Diels-Alder Reaction of Anthracene with Maleic Anhydride 2 Introduction: The purpose of this experiment is to form 9, 10-dihydroanthracene-9,10-α, β-succinic anhydride by way of a Diels Alder reaction between anthracene and maleic anhydride. Anthracene acts as the diene and maleic anhydride functions as the dienophile.

a. First you need to find the molar mass:-look up on the periodic table what is called the atomic weight or molar mass (should be under the symbol). This is the number of grams in one mole of this element. -C: 12.01 g I'm wondering why maleic anhydride adds to the middle cycle of anthracene, and not the outer two. I would have expected that a Diels–Alder with the outer ring would be better, because I expected a naphtalene part to be lower in energy than two benzene parts (more resonance stabilisation).
