41+ Benzene Ring Mass Spec Pics. The molecular formula of the compound under analysis is c8h8o2 = mr of 136 the mass spectrum shows the peak at 91 to be the most stable. Moist heat (poor to excellent, with syndiotatic styrene);
Mass Spectrometry from www2.chemistry.msu.edu
Hence it is attached by electrophile, generally. In benzene, the atoms are hydrogens. The positive fragments which are produced (cations and radical cations).
For now, the classic example of an aromatic compound is benzene, seen below with its 1h nmr spectrum.
In mass spectrometry, a substance is bombarded with an electron beam having sufficient energy to fragment the molecule. The benzene rings a and b derived from the h nmr spectrum can be completed using table 41.1. Hence it is attached by electrophile, generally. Learn about this topic in these articles
