  1. Given for an unknown compound are MS and IR spectra. You are to determine the structure of the compound, provide a fragmentation reaction—meaning mechanism–from the molecular ion giving the base peak, and identify two bands (give frequencies and functional group) in the IR consistent with your proposed structure
