(a) Interpretation: The diene that would react with ethene to produce the given compound is to be drawn. Concept introduction: The Diels-Alder reaction is the cycloaddition of diene and dienophile. The diene has a pair of conjugate double and contributes its 4π electrons. The dienophile has single double bond and contributes its 2π electrons. These six electrons must flow in a cyclic fashion. Thus, the reaction proceeds through a cyclic transition state, which makes it a pericyclic reaction. Therefore, the Diels-Alder reaction is called [4+2] cycloaddition. The carbons from the diene have C=C bond in the six membered ring product.
