1. Write an equation for the Diels - Alder reaction of cyclopentadiene and 1,4-benzoquinone. 2. Draw the structures for the "endo" and "exo" products from the reaction of cyclopentadiene with maleic anhydride. 3. What are the products of the following Diels -Alder reactions? (Show the stereochemistry where applicable.) a) b) 4. The Diel- Alder reacion is said to be "stereospecific." What does that mean in terms of product in each reaction in part a. 5. In this experiment you will react cyclopentadiene (the diene) with maleic anhydride (the dienophile) to produce the bicyclic compound, endo-bicyclo[2.2.1]hept-5-ene-2.3-dicarboxylic anhydride. The endoadduct is formed exclusively. Why
