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?

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?
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 percent yield for this Diels-Alder lab report? It was a reaction that included cyclopentadiene, and maleic anhydride that formed cis-norbornene-5,6-endo dicarboxylic anhydride. The percent yield I keep calculating ends up to be 107% which I know is incorrect. Here's my data: Used 0.01205g of maleic anhydride and used 0.10mL of cyclopentadiene. The weighted final product (cis-norbornene-5,6-endo dicarboxylic anhydride) was 0.0820g I know that the limiting reagent is the cyclopentadiene. We also used 0.4mL of ethyl acetate and...

I did an organic chemistry lab using the Diels-Alder reaction with anthracene-9-methanol, N-methylmaleimide, and water. I started with 0.066 g of anthracene-9-methanol, 25 mL of deionized water, and 0.070 g of N-methylmaleimide. How would I calculate the percent recovery of the product? (not the percent yield)
for this experiment i got a yield of 0.93g
how do you and what is the theoretical and percentage
yield?

I need help calculating theoretical yield for my
Diels-Alder lab experiment. This reaction was between 1,3-butadiene
and maleic anhydride, forming cis 1,2,3,6-tetrahydrophthalic
anhydride. In this experiment 1.0g of maleic anhydride was combined
with 1.8g 3-sulfolene and 2 mL dry xylene and refluxed for 30 mins.
6 mL of xylene was added to dissolve solids and then decanted, then
warm pet. ether was added to form crystalline product after
cooling. some of this info may be irrelevant in what is needed...
