Recall that the first step in the SN1 is that the leaving group leaves to give a carbocation. ... Therefore, a rearrangement can occur to give the more stable tertiary carbocation, which is then attacked by the nucleophile (water in this case).
Do rearrangements occur in E1 reaction?
3. Elimination (E1) With Rearrangement: Alkyl Shift. You might remember that these types of rearrangements can occur in SN1 reactions too. And if you read that post, you might recall that in addition to shifts of hydrogen (“hydride”, because there's a pair of electrons attached) we can also have alkyl shifts.

Does rearrangement occur in E2?
E2 reactions are regioselective and favor the formation of Zaitsev products. 2 mechanisms in how the identity of the base, the leaving group and the solvent affect the rate. The base appears in the rate equation, so the rate of the E2 reaction increases as the strength of the base increases.
