should be qualitatively reliable for the nonconjugated cations (entries 4-6, 13, 14, 16, 17, 19, and 20). The *-donor effect of the cyano group is rapidly attenuated with successive introduction of methyl groups (entries 1-3). That is, the most stable cations are destabilized most by the cyano group. This occurs since the inductive effect drops off only(More)
