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).
Why do aldehydes, esters, and amides all have a strong absorption in the 1630-1780 cm1 region of their IR spectra? A) The bond between H and the sp³-hybridized C in these functional groups vibrates in this energy range. B) Each of these functional groups has at least two resonance structures, and the different vibrations of the resonance structures give off energy in this region. C) The bond between O and the sp²-hybridized C in these functional groups vibrates at a frequency in this energy range. D) Light at this wavenumber causes the average C to O bond length to increase which causes more of this light to be transmitted. E) An electron in the bond of these functional groups gets excited to the * orbital.
