A compound displays a prominent peak at 3400 cm in its IR spectrum. The mass spectrum has a molecular ion with m/z of 74. The base peak at m/z = 45. Draw a structure that best fits this data. OH Select to Edit In mass spectrometry, McLafferty Rearrangements are common in carbonyl compounds. Draw the daughter ion that would be observed in the mass spectrum resulting from McLafferty Rearrangement of this molecule. Select to Draw
