5. Below are two 'H NMR spectra of the starting materials (furan and maleic anhydride). Assign the compounds to their correct spectra by drawing the corresponding structure on the NMR and assign the peaks (resonances) to the correct protons in the structure. (Note: the numbers above each peak is it integration value, while the number belnw tha nash in s. - 9. The following questions will pertain to the the single- \( \mathrm{X} \) ray structure of the Diels-Alder product shown below. a. Draw the overall mechanism of the Diels-Alder reaction with furan and maleic anhydride, drawing the product with the correct regio- and stereo-chemistry based on the \( \mathrm{X} \)-ray structure shown above. b. Is the product the expected endo or the unexpected exo product? c. Circle the new bonds on the structure above that were formed in the reaction. d. Circle the portion of the structure that was derived from the furan starting material.
