Please draw the structure in the box that is consistent with all the spectral data and
alphabetically label all of the equivalent protons in the structure (Ha, Hb, Hc....) in order to assign all
the proton NMR peaks. The integrations are computer generated and approximate the number of
equivalent protons. Molecular formula: C13H1802
