1.) What IR spectral features were common to phenylacetylene and butyronitrile? How did you distinguish them? Which spectral features allowed you to distinguish

2.) Which IR spectral features allow you to distinguish between acrolein and methyl vinyl ketone?

3.) Which IR features tell you that you have a nitro group? Devise an experiment involving LiAlH 4 reduction and IR spectroscopy to definitively determine the existence of a nitro group in your compound.

4.) Which two compounds (among those 10 IR practice problems) show extensive evidence of hydrogen bonding in their IR spectra? Which signature tells you that an amide is primary versus secondary? Would you expect to see hydrogen bonding in pure dimethylformamide? 4.) Which two compounds (among those 10 IR practice problems) show extensive evidence of hydrogen bonding in their IR spectra?
