Bicyclic diene A reacts readily with appropriate alkenes by the Diels-Alder reaction, whereas diene B is totally unreactive. Explain. b. Write the three reactions and show the product for diene A reacting with dienophiles I, II, and III. Rank I, II, and III in terms of their expected reactivity in a Diels Alder reaction.
