Recall (Section 16-10) that two positions of anthracene sometimes react more like polyenes than

like aromatic compounds.

(a) Draw a Kekulé structure that shows how the reactive positions of anthracene are the ends of adiene, appropriate for a Diels–Alder reaction.

(b) The Diels–Alder reaction of anthracene with maleic anhydride is a common organic lab experiment. Predict the product of this Diels–Alder reaction.
