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). (...

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?

Hello.. could you please help me label the peaks on H NMR and
13C spectra. The compound is
4-Methyl-2,6-bis(4-methylbenzylidene)cyclohexanone.
Thank you!
I had to determine the product based off ketone and aldehyde
reactants. The product could be incorrect. I was only given NMR and
13C spectra to determine reactants and product. Sorry for
confusion! Thanks

Assume, that when bromine is added to the product, the resulting
mixture is colorless. If potassium permanganate is added to the
product, the formation of a brown precipitate is observed.
