In this mass spectrum, which peak most likely represents the molecular ion?
Homework Answers
The problem is based on the concept of identification of molecular ion peak in the mass spectra.
Mass spectrometry is used for the analysis of mass of the compounds.
Mass spectroscopy is an analytical technique which is used for the mass determination of the compounds. In the mass spectrometry, the compounds are ionized and the molecular radical cation is generated which is unstable and breakdown in certain fragments according to their charge to mass ratio . The peak having highest value is the molecular ion peak.
The represents the fragmented peaks. The peaks represents the radical cation. Therefore, the peaks are not the molecular ion peak.
The peak having highest value is the molecular ion peak. Therefore, represents the molecular ion peak.
Ans:The represents the molecular ion peak in the mass spectra.
