Unformatted text preview: tion state. The Hammond Postulate states that the stability of the reaction intermediate
should lead to lower activation energy and a faster rate of reaction.1 The solvent in the reaction
has that effect on the SN1 reaction. In the process of solvation, the solvent molecules surround
the carbocation, which has a positive charge on the central carbon, illustrated again in Figure 1.
The solvent molecules can stabilize the carbocation transition state by distributing the electron
density with electron-rich, or po...
