For SN1 rxns, when the carbocations forms, will the plus charge move to the most stable location before the nucleophile attaches?

For E1/E2 rxns, if I get the solvent CH3OH/CH3O-, is it E1 or E2?

Thanks!

1) Yes! For SN1 reactions, rearrangement is possible so the plus charge would move to make the most stable carbocation.

2) If you have CH3O-, which is a strong nucleophile or a strong base, it either goes thru E2 or SN2. So to answer your question, it would be E2! If you only have CH3OH then it would be E1 I believe

Thanks @urbanthread, I was confused with the elimination question because I know that any O- is going to go through E2/SN2, but since the CH3OH was first and then CH3O-, I thought it was E1.
