UV-Vis, IR, NMR, and mass spectrometry are spectroscopic tools we use to obtain structural information about compounds. For each pair of compounds below, describe at least one aspect from each of two spectroscopic methods (UV-Vis, IR, NMR, or mass spectrometry) that would distinguish one compound in a pair from the other.
(a) 1,3-Butadiene and 1-butyne
(b) 1,3-Butadiene and butane
(c) Butane and
