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.

How would I calculate the theoretical yield of
endo-cis-norbornene-5,6-endo-dicarboxylic anhydride and
endo-cis-norbornene-5,6-dicarboxylic acid? Can you please show me
step by step? Can you show me the balanced chemical equation (with
molecular formulas, not the pictures) with the mole ratios as well?
How do we figure out the limiting reagent? Can you also show how to
convert mL to grams for cyclopentadiene, if needed?
We used:
2g of maleic acid
6mL of ethyl acetate
6mL of ligroin (hexanes)
2mL of cyclopentadiene...

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...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
