Which step is faster? Carbocations are not necessarily short‐lived intermediates in solvolytic displacement reactions. In many cases, ionization of the carbocation's precursor is faster than the subsequent reaction with the solvent (see scheme), which allows one to directly observe the intermediate carbocation.
