Concept explainers
Interpretation:
Whether the compound that produced the spectrum shown in the problem contains Cl, Br, or S is to be determined.
Concept introduction:
In a mass spectrometer, the molecules of the compound are bombarded with high energy electrons. This generally results in one electron from the molecule being knocked out. The resulting ion is a radical ion with an odd number of electrons, called the molecular ion. Since the mass of an electron is negligible, the mass of the molecule and the molecular ion are essentially the same.
The molecular ion is a high energy species and breaks up into a number of fragments, one of which carries the charge. Another source of fragmentation is the bombarding electrons themselves. These electrons often have energies sufficient to not just knock out an electron but also enough to break bonds.
The only species detected in the mass spectrometer are the charged species and their separation is based on the
The mass spectrum shows the distribution of the relative abundance of various ion fragments as a function of their
