Explain why the
IR corresponds to a particular compound of those that are possible
based on BP and why it couldn't be any of the others -mention at
least 3 IR peaks that are present that correspond to functional
groups in your molecule, and discuss specific peaks that were
either present or absent that allowed you to rule out the other
compounds possible based on the boiling point. Reference your IR
spectra as figures.
