- Chlorinated compounds show an M+2 peak that is 1/3 as large as the M+ peak.
Note also that halogens are easily lost during mass spectrometry. If you subtract the mass of the halogen from the molecular ion mass, you will often find a peak that corresponds to the remainder of the structure.
Problem MS4.
Draw one possible structure for the compound in each of the following mass spectra.
