Quizplus · Accepted Answer

A typical Diels-Alder reaction involves an electron-rich diene and an electron-poor dienophile. This is because the reaction is a concerted cycloaddition, where the diene acts as a nucleophile and the dienophile acts as an electrophile. The electron-rich diene donates its electrons to the electron-poor dienophile, which leads to the formation of a new six-membered ring.
