Show all steps and arrows (6 pts) H-SO4 heat H3C он CH3 CH3 Diels-Alder reactions involve some further stereochemical considerations that we did not talk about. Mainly, these are the formation of the endo and the exo products (starting page 361 of the book). Using the example below, explain the difference between the endo and the exo products.

Dehydration Experiment: 1. Show all appropriate electron-pushing arrows to explain the formation of each of the observed products in the following reaction. Because intermediates have been provided for you, all arrows must be perfect and must be clear to get credit. 9M H,SO 20- s-d-o g- 2. "Rearrangements" like you see above are fairly common in Snl (and El) reactions, but are never seen in Sy2 or E2 reactions. Why don't those latter mechanisms ever allow rearrangement to occur?
