D Question 3 3 pts (This is the same reaction from #2.) You repeat the Diels-Alder reaction from lab using 3.4 g of maleic anhydride (98.06 g/mol) and 2.5 g of cyclopentadiene (66.1 g/mol) to form the final solid product (164.16 g/mol). All compounds are in a 1:1 ratio in the balanced equation. Assuming all the limiting reagent reacts, how much of the other reagent is there in excess? 0.469 g 0 0.309 g O 1.71 g O 0.208 g...

1. What if you were trying a 6+2 diels alder reaction to form an eight member ring? Would it be successful? Is there constructive overlap? Will the symmetry allowed reaction occur? 2. What about an 8+2 reaction? Will a symmetry allowed reaction occur? 3. Draw the HOMO of the whichever of the above reactions was symmetry forbidden and determine if the reaction would be photochemically allowed.
