(a) Interpretation: Which isomers of C 10 H 14 with two fused six-membered rings will react with ethene in a Diels–Alder reaction and which will not is to be determined. 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 two C=C bonds in diene must be conjugated and able to attain the s -cis conformation. The Diels–Alder reactions cannot take place with the diene in the s -trans conformation. In s -cis conformation, the two ends of the π system point in nearly the same direction, and in s -trans conformation, the ends of the two reacting species are farther apart.
