I am trying to find the percent yield of my final product in a Diels-Alder reaction. The weight of our final endo product (Cis-norborene-5,6-endo-dicarboxylic anhydride) was 5.025 grams. When performing the reaction, we used 2.5 grams of maleic anhydride and 2.5mL of cyclopentadine. Assume average molecular weight for the reagents.

Expert Solution

maleic anhydride + cyclopentadiene ------------------> Cis-norborene-5,6-endo-dicarboxylic anhydride

2.5 g 2.5 ml 2.5 g

Diels-Alder reaction is auto-economy reaction . there is no loss in reactants. so the reactant mass totally converts into products.

percent yield = (actual mass / theoritical mass ) x 100

= (2.5 / 5.025) x 100

= 49.75 %

Calculate the atom economy and reaction efficiency for the Diels Alder reaction.

Calculate the atom economy and reaction efficiency for the Diels Alder reaction. For the reagents, consider only the mass Mol. wt. of the 9-anthracenemethanol and N-methylmaleimide. Use proper significant figures, units and show all work. Atom economy (Mol, wt, desired product/combined Mol, wt. of all reagents) Reaction efficiency = atom economy x percent yield

The Diels-Alder reaction is one of the most useful in organic chemistry because it allows for the formation of rings: The reactor initially has only the diene and the dienophile. The product stream has 55 mole% of the ring and 17 mole% of diene. Calculate the fractional conversion of the limiting reactant and the percentage by which the other reactant is in excess. If we assume that we can do this reaction continuously, pick a basis for the feed and...
