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.

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?
What is the theoretical yield of 9,10-dihydroanthracene-9,10-α,β-succinic anhydride in your synthesis? 0.113 g maleic anhydride (98.06 g/mol) 0.209 g Anthracene (178.23g/mol) 9,10-dihydroanthracene-9,10-α,β-succinic anhydride (276.29g/mol)
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).
Which is more polar anthracene or 9,10-dihydroanthracene-9,10-α,β-succinic anhydride?
I am writing my chem lab report for the Diels Alder reaction, using 80mg of anthracene and 40mg of maleic anhydride to form 9,10-dihydroanthracene-9,10-a,B-succinic acid anhydride. The question I'm stuck on is why does the yellow color disappear from the reaction by refluxing the two compounds together?

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).

How many g of anthracene would you need to react with 9.8 g of maleic anhydride in a Diels-Alder reaction? (Assume a 1:1 molar ration of anthracene to maleic anhydride.) 2 - If you started lab using 0.221 g of anthracene and 0.652 g of maleic anhydride, and obtained 0.182 g of product, what is the percent yield?
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.
