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).
The given reaction is a cyclo addition reaction between diene and a dienophile.Here anthracene acts as diene and Maleic anhydride acts as dienophiile .The reactions are expressed as follows;
Theorectical and percentage yield are calculated as follows;
Limiting reagent;
One mole of anthracene is 178.23 gms
0.6gms of anthracene is 0.0033 moles
One mole of maleic anhydride is 98.06 gms
0.3 gms of maleic anhydride is 0.0030 moles
As the number of moles reacting is less for maleic anhydride it functions as limiting reagent Theoretical Yield
One mole of maleic anhydride gives one mole of the adduct
ie. 98.06 gms of maleic anhydride gives 276.29 gms of the adduct
So 0.3 gms of maleic anhydride gives 276.2/ 98.06 * 0.3. =0.85 gms of adduct
Percentage yield
Actual yield/Theoretical yield* 100 = 0.7/ 0.85 *100 = 82.35%

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?
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?
start with 0.6 of anthracene and 0.3 g of maleic anhydride and we get 0.72 g of 9,10-dihydroanthraceno-9,10-endo-,-succinic anhydride what is the % yield ?
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.
(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
Write a reaction scheme and structures for the diels-alder reaction to 0.8 g of anthracene and 0.40g of maleic anhydride and add 10 mL of p-xylene
diels alder reaction Draw a structure for the exo product formed by cyclopentadiene and maleic anhydride. Because the exo form is more stable than the endo form, why is the endo product formed almost exclusively in this reaction? In addition to the main product, what are two side reactions that could occur in this experiment? The infrared spectrum of the adduct is given in this experiment. Interpret the principal peaks.
