Question
Chapter 6, Problem 6.53P
Interpretation Introduction
Interpretation:
Considering the given example which depicts the Diels-Alder reaction it should be predicted that whether the reaction is exothermic or endothermic reaction.
Concept Introduction:
Exothermic reaction: Exothermic reactions are those reactions in which heat energy is released during the reaction.
Endothermic reaction: Endothermic reactions are those in which heat is absorbed during any
Diels-Alder reaction: It is the reaction between the conjugated diene and dienophile which results in the formation of new compound which is substituted cyclohexene derivative.

Diels–Alder reaction of a monosubstituted diene (such as CH2=CH– CH=CHOCH3) with a monosubstituted dienophile (such as CH2=CHCHO) gives a mixture of products, but the 1,2-disubstituted product often predominates. Draw the resonance hybrid for each reactant, and use the charge distribution of the hybrids to explain why the 1,2-disubstituted product is the major product.
Is the following true or false?
To catalyse a Diels-Alder reaction a common approach involves the use of a Lewis acid capable of lowering the LUMO of the dienophile.
Can someone draw the arrows for this reaction so I can understand how the product was formed? I'm having trouble understanding that aspect of the Diels-Alder reaction.
