(Diels-Alder reaction of anthracene with malice anhydride) Calculate the percent yield of your product before and after recrystallization. Compare the percent yields and explain why they are not the same. 100 mg anthracene 55 mg maleic anhydride product before recrystallization: 0.083 g product after recrystallization: 0.038 g
Reaction is Diels-Alder Reaction: 0.6 g (Anthracene) + 0.3 g (maleic anhydride) --> product [9,10-dihydroanthreceno-9,10-endo- α, β-succinic anhydride] 0.70 grams obtained. When vacuumed, xylened and isolated, the product yielded 0.70 grams product. Please show how to calculate % yield with the weights above (Theoretical + Actual).
What is the complete Infrared Spectrum of 9,10-dihydroanthracene-9,10-α,β-succinic anhydride, in the diels-alder reaction of Anthracene With Maleic Anhydride?
Calculate the theoretical yield of the Diels-Alder reaction between anthracene (100 mg) and maleic anhydride (55 mg). Which is the limiting reagent ? Show all calculation steps.
Calculating the theoretical yield for a Diels-Alder reaction: Reactants: 0.555 g of butadiene sulfone (MW = 118.15 g/mol) 0.305 g of maleic anhydride (MW = 98.06 g/mol) 1 mL of Xylene (MW = 106.16 g/mol) (density = 0.866 g/mL) 2 mL of Hexane (68 g/mol) Product: cis-4-cyclohexene-1,2-dicarboxylic acid anhydride (MW = 152.15 g/mol)
Diels-alder reaction lab Reaction: anthracene+ maleic anhydride <---> 9,10-Dihydroanthracene-9,10-α,β-succinic acid anhydride How would raising the temperature of the experiment affect product isolation? Would more or less product be expected, and why?

Attach a water-cooled condenser and reflux for 60 minutes. Allow the solution to cool to room temperature and then place the flask in...
Draw and discuss the mechanism (with arrows to show electron movements) of the Diels-Alder reaction between anthracene and maleic anhydride. Draw the orientation and phases of the reacting p-orbitals showing how they overlap in a “suprafacial” geometry to form the product
There are three possible products for the Diels-Alder reaction, each involve the addition of one molecule of maleic anhydride to one molecule of anthracene. Draw each possible product, clearly showing the stereochemistry of the reaction.
