document E1 Mechanism of Elimination
E1 indicates an elimination, unimolecular reaction, where rate = k [R-LG]. This implies that the rate-determining step of the mechanism depends on the decomposition of a single molecular species.   Overall, this pathway is a multi-step process with the following two critical steps:...

document Student Question: Rearrangement in E1 and E2 - When does rearrangement occur in alcohol dehydration? When does it occur in alkyl halide dehydrohalogenation? For example, can rearrangement change a primary carbocation to a tertiary carbocation? Would that allow the reaction to have an E1 mechanism instead of an E2?
When does rearrangement occur in alcohol dehydration? Because alcohol dehydration is an elimination reaction, rearrangement occurs when a carbocation intermediate or partial carbocation (as in the transition state of an E2 type dehydration) occurs during elimination.  If this carbocation...
