3) 3) (12 points) The IR spectra shown below are all for molecules with molecular formula C4H.NO. For each spectrum, propose a structure in the box to the right that is consistent with the IR features. Pay attention to things that ARE there and, maybe more importantly, things that are NOT present in the IR spectrum (and hence, should not be part of your molecule). 100 - 2000 see 1000 AVENUMBERTI BAVENUMERI
