To determine: The logical fragmentation reactions to account for the given ion observed in the mass spectra.
Interpretation: The logical fragmentation reactions to account for the given ion observed in the mass spectra are to be given.
Concept introduction: Mass spectroscopy provides a reliable molecular weight for an unknown compound and also gives us the information about the molecular formula as well.
Fragmentation gives the resonance stabilized cations whenever possible. Loss of a small molecule is usually indicated by a fragment peak having an even mass number corresponding to loss of an even mass number. Fragmentation produces the most stable carbocation and radicals when occurs in
