WebYou’ve come across examples above where the leaving group is mostly a halide or sulfonate anion. Recall that conditions for substitution of an alcohol involve protonation of the alcohol first, then loss of water as a leaving group to generate a carbocation. WebElimination Reactions. E1 Reaction Mechanism and E1 Practice Problems. The E1 is a stepwise, unimolecular – 1st order elimination mechanism: The first, and the rate-determining step is the loss of the leaving group forming a carbocation which is then attacked by the base: This is similar to the S N 1 mechanism and differs only in that …
