Stoichiometric Data (For any reactants that are part of the balanced equation, base on the amounts measured in lab)
Figure 3-sulfolene
Figure IR spectrum for cis-4-Cyclopentant – 1,2 dicarboxylic acid anhydride
Figure from experiment in the text
NMR 1 from lab results endo norbornene-cis-5,6 dicarboxylic anhydride
Figure 2 from lab results the exo norbornene-cis-5,6 dicarboxylic anhydride (less stable)

Discussion
Figure 1.The diene (1,3 butadiene) plus the ethane (sulfolene) produce a cyclohexene (either the endo or exo isomer depending on reaction conditions).
Figure 2. Under acidic conditions to sulfuric acid the endo isomer plus water form the less stable exo isomer
