- Write a general rule that can be used to predict the major product of a Diels–Alder reaction between an alkene with an electron-withdrawing substituent and a diene with a substituent that can donate electrons by resonance depending on the location of the substituent on the diene.arrow_forwardSelect the product this Diels-Alder reaction?arrow_forwardWhy does the diels alder reaction often show high selectivity and predictable stereochemistry?arrow_forward
- Which combination of reactants would undergo a Diels-Alder reaction the most quickly?arrow_forwardwhat is the product after these compumds undergo a diels-alder reactionarrow_forwardA2 What is the inverse electron demand Diels–Alder reaction? Please pick a pair of a diene and a dienophile from the following dienes and dienophile that will undergo this type of reaction. Please show how this reaction works using Frontier Molecular Orbitals. What is the reaction product?arrow_forward
- Rank the following dienes in their rate of reaction with the same dienophile in a Diels-Alder reaction. For example, 1 = fastest or most reactive diene, 4 = slowest or least reactive diene.arrow_forwardDraw the structures of the diene and dienophile that would be used in the diels alder reaction to synthesize the following compounds. Label each structure as diene or dienophile.arrow_forwardComplete the Diels-Alder reactions by drawing structures for the products in each question.arrow_forward
