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...
Endo-norbornene-cis-5,6-dicarboxylic acid can be converted back into its anhydride precursor by treatment with anhydrous acid. Propose a mechanism for this reaction.
Reaction 0 Maleic anhydride mp 53°C, MW 98.06 cis-Norbornene-5,6-endo-dicarboxylic anhydride mp 165°C, MW 164.16 Problem: 1) You are given 1 mL of freshly distilled cyclopentadiene in a clean vial and I g of maleic anhydride in weigh boat. The mass of the final product is 1.1g. A) Calculate percent yield. B) Interpret IR spectrum of product (shown below) and provide a table listing functional groups and peak intensity, 5. Which of the following dienes are s-trans and which are s-cis?...
1. Look online to find the IR spectrum of cis-norbornene-5,6-endo-dicarboxylic anhydride: what do the signals at 1759 cm-1 and 1838 cm-1 indicate?
Examine the IR spectrum of cis-norbornene-5,6-endo-dicarboxylic anhydride, (Fig.48.8, pp. 630): what do the signals at 1750 cm-1 and 1838 cm-1 indicate?
- vivUINUAR 3) Why is cyclopentadiene more reactive ntadiene more reactive with maleic anhydride than with itself? chiral centers does endo-norbornene-cis-5,6-dicarboxylic acid possess? Is the 4) How many chiral centers does endo molecule itself chiral?

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?
1.
Examine the IR spectrum of cis-norbornene-5,6-endo-dicarboxylic
anhydride, (Fig.48.8, pp. 630): what do the signals at 1750 cm-1
and 1838 cm-1 indicate?
2. Explain the following questions regarding the possible
contamination of the final isolated product with dicyclopentadiene
(the cyclopentadiene dimer).
a. Since “cracked” cyclopentadiene can spontaneously dimerize
back to dicyclopentadiene, could the dimer be formed as an unwanted
“by-product” during the experiment?
b. How does the experimental procedure minimize contamination of
the final isolated (desired) product with this (undesired)...
1. Examine the IR spectrum of cis-norbornene-5,6-endo-dicarboxylic anhydride, (Fig.48.8, pp. 630): (this is out of macroscale and microscale organic experiments 6e textbook can be googled to view) what do the signals at 1750 cm-1 and 1838 cm-1 indicate? (please include functional groups, structures, as much as possible so i can understand it) Thank you!
