Chapter 15, Problem 64SP(choose chapter or problem)
An unknown compound gives a mass spectrum with a weak molecular ion at \(m / z 113\) and a prominent ion at \(m / z 68\). Its NMR and IR spectra are shown here. Determine the structure, and show how it is consistent with the observed absorptions. Propose a favorable fragmentation to explain the prominent MS peak at \(m / z 68\).
