How many g of anthracene would you need to react with 9.8 g of maleic anhydride in a Diels-Alder reaction? (Assume a 1:1 molar ration of anthracene to maleic anhydride.) 2 - If you started lab using 0.221 g of anthracene and 0.652 g of maleic anhydride, and obtained 0.182 g of product, what is the percent yield?

The following 1H NMR spectra represent the composition of the products submitted by two groups of students after completing the Diels Alder reaction between cyclopentadiene and maleic anhydride. a Which product looks purer? ( 1 point) b What impurities appear to be present in the other sample? ( 1 point ) C What purification technique involving a “solvent pair” might be used to purify the impure product? Briefly explain how you would carry out such a purification (experimental procedure). (...

Theoretically, can you tell the difference between the maleic anhydride and the product by their IR spectra? Can you distinguish the anhydride cycloadduct from the hydrolyzed di-acid product? Explain. The product obtained was cis-4-cyclohexene-1,2-dicarboxylic anhydride.

a. Draw a curved arrow mechanism for the formation of the diels alder product you obtained by combining alpha-phellandrene and maleic anhydride. b. How many possible diels alder products could be formed in this reaction (draw them and state how they are related to each other)? c. Which one is formed as the major product in the reaction and why?
