The structures and the mechanism of fragmentation that corresponds to ions with m/z 57 and 41 in the mass spectrum of 4-methyl-1-hexene are to be proposed. Concept introduction: Cleavage of a single bond produces a cation and a radical. The Cation can be detected using positive ion mass spectrometry and since the radical is not charged, it will be undetected. Chain branching or cleavage of a single bond at branch points will occur such that the carbocation formed is more stable. In simple words, the stability of carbocation determines the fragmentation pattern. Alkenes ionize and undergo fragmentation to form resonating allylic cations
