Carbon monoxide [CO] exhibits an IR absorption at 2143cm-1, acetone [CH3C(O)CH3],exhibits an IR absorption for the CO vibration at 1715 cm-1 and ethanol [CH3CH2OH] exhibits an IR absorption for CO at ~1150 cm-1. Draw Lewis structures of these three molecules and use your structures to explain the observed differences in the CO IR absorption peak frequency (nCO).
