E1 & E2 Reactions
« on: May 31, 2005, 04:19:32 AM »
e.g.

(Me)3C-Br + KOH + ethanol + heat <=> alkenes + KBr

Which mechanism is dominant, E1 or E2?

Is there any effect on eliminations using polar protic solvent when strong base is used?

Thank you very much!

But I still want to know the reason why polar protic solvent doesn't affect E1 and E2 reactions.
It can stabilize the carbocation in E1 and shielding the base (reduces basicity) in E2.
