(a)
Interpretation:
- The products for the given Diels-Alder reactions have to be predicted.
Concept Introduction:
Diels-Alder reaction:
A conjugated diene reacts with a compound containing a carbon-carbon double bond. It is a cycloaddition reaction, where two reactants form a cyclic product.
Rule: The stabilities of carbocation are,

- The Diels–Alder reaction, a powerful reaction discussed in Chapter 14, occurs when a 1,3-diene such as A reacts with an alkene such as B to form the six-membered ring in C. a.Draw curved arrows to show how A and B react to form C. b.What bonds are broken and formed in this reaction? c.Would you expect this reaction to be endothermic or exothermic? d.Does entropy favor the reactants or products? e. Is the Diels–Alder reaction a substitution, elimination, or addition?arrow_forwardi need help answering queshtion for Diels-Alder Reactionarrow_forwardHow do you use pyride for the Diels-Alder reaction?arrow_forward
