WebWhatever its source, a parent molecular ion, M+, has one unpaired electron and is properly described as an odd-electron ion (a radical cation). When a parent molecular ion fragments, it does so homolytically, as shown in Equation 23-2, and produces a radical and an ion in which the electrons are paired—an even-electron ion. WebFundamentally, in the attribution process, assuming that positive ions are protonated molecules [M+H] + and negative ions are deprotonated molecules [M-H] -, it is verified …
