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.
the boiling point for unkown 2: 66-67c
unknown 3: 100-102c

unknown is. Based off my many tests, the unknown has multiple bonds
and a boiling point of 39-41 degrees celsius. Attached is the IR
