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

- Challenging samples: 1. Metal complexes with low volatility are often difficult to analyze when performing atomic absorption measurements because the atomization efficiency is reduced to unacceptably low levels. Devise a strategy or strategies for eliminating the problem of a non-volatile metal complex? Explain how you would do that. 2. Devise a strategy to overcome unwanted ionization of the analyte? Explain what it would be. 3. Devise a general method that can be used to account for the presence of unknown matrix effects.arrow_forwardDon't used hand raitingarrow_forwardDon't used hand raiting don't used Ai solutionarrow_forward
