WebSn1 reactions depend on the stability of the cation formed when the Leaving group had left. So, since tertiary carbocations are most stable of the three will undergo Sn1 reaction … WebThe slow step of this mechanism is the formation of a carbocation intermediate. These types of intermediates are unstable, so anything that we can do to stabilize them will help them form faster.-R groups stabilize carbocations through a phenomenon called hyperconjugation. Meaning that the more substituted the carbocation, the more stable it is.
