The M+ values for ?-chloroacetyl chloride, ?-chloro-2,6-dimethylacetanilide, and lidocaine are 112, 197, and 234 m/z, respectively. For each of these three chemicals, state how the "parity rule" is (or is not) obeyed by the MS data. If this question cannot be answered for a chemical, state briefly why not (for example, what additional data would be needed or why the situation is ambiguous).
