How would I calculate the theoretical yield of
endo-cis-norbornene-5,6-endo-dicarboxylic anhydride and
endo-cis-norbornene-5,6-dicarboxylic acid? Can you please show me
step by step? Can you show me the balanced chemical equation (with
molecular formulas, not the pictures) with the mole ratios as well?
How do we figure out the limiting reagent? Can you also show how to
convert mL to grams for cyclopentadiene, if needed?

8) (E)-4-methylpenta-2,4-dien-1-ol and cyclopent-4-ene-1,3-dione can undergo a Diels Alder type reaction. First, draw the Huckel M.O. diagram for this system. Indicate which orbital is the HOMO and which is the LUMO for the diene and dienophile. Second, clearly sketch the cartoons that show which orbitals interact to allow cyclization. Based on your analysis, is this reaction allowed by heating? (15 points) (E)-4-methylpenta-2,4-dien-1-ol a OH + cyclopent-4-ene-1,3-dione

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...
