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 0.4mL of ligroin but I don't think that contributes to the calculations.

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 the preparation of cis-Norbornene-5,6-endo-dicarboxylic anhydride from cyclopentadiene and maleic acid in the presence of ethyl acetate and ligroin?

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.
