E1cb reactions
WebE1cB Eliminations! A different type of elimination involves a base abstracting a proton in the rate determining step and is called E1cB (elimination, unimolecular, conjugate base)! LG base LG E1cB is also a two-step reaction like E1, but the steps are reversed! (first step is loss of hydrogen and second step is loss of leaving group)!
