Is Rearrangement Possible in E2?

1,2-Hydride shifts and 1,2-methyl shifts will occur in E1 reactions if the rearrangement leads to a more stable carbocation. These rearrangements do not occur for obvious reasons in the E2 reaction.

Is rearrangement possible in elimination?

3. Elimination (E1) With Rearrangement: Alkyl Shift. You might remember that these types of rearrangements can occur in SN1 reactions too. ... This pretty much does it for elimination reactions.

Is rearrangement possible in E1 reaction?

In an E1 reaction, the rate determining step is the loss of the leaving group to form the intermediate carbocation. ... Since carbocation intermediates are formed during an E1, there is always the possibility of rearrangements (e.g. 1,2-hydride or 1,2-alkyl shifts) to generate a more stable carbocation.
