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?
The reaction when run at high temperature would increase the rate of the reaction thus producing higher product.

Draw the complete reaction mechanism for the below. (R groups are not acceptable, please draw the complete structure for every step.) Diels Alder reaction between one mole of anthracene (molecular weight = 178.23g/mol) and one mole maleic anhydride (molecular weight = 98.06g/mol) forms one mole of 9,10-dihydroanthracene-9,10-α,β-succinic anhydride (molecular weight = 276.29g/mol).

The Diels-Alder reaction you will conduct in this experiment is between cyclopentadiene and maleic anhydride (the anhydride of cis-2-butendioic acid): diene dienophile The glassware is predried and a drying tube is used to prevent the hydrolysis of maleic anhydride to maleic acid (cis-2-butendioic acid): On heating, maleic acid isomerizes to fumaric acid (trans-2-butendioic acid). Show the mixture of products that would be formed if a small amount of moisture was present in the Diels-Alder reaction you have performed.
(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
