Question

Which of the following statements about the Diels-Alder reaction is true? Multiple Choice The diene can react only when it adopts the s-trans conformation. Electron-withdrawing substituents in the diene increase reaction rate. Electron-donating substituents in the dienophile increase the reaction rate. The stereochemistry of the dienophile is retained in the product.

Answer 1

Answer:

The stereochemistry of the dienophile is retained in the product.

Explanation:

The main properties of the Diels-Alder reaction are:

• The diene can react only when it adopts the s-cis conformation.

• Electron-donating substituents in the diene increase reaction rate.

• Electron-withdrawing substituents in the dienophile increase reaction rate.

• The stereochemistry of the dienophile and of the diene is retained in the product.
