E1 reaction with oh
Did you know?
WebWhen an alcohol is dehydrated through an E1 reaction, two alkene molecules are created. The slow step of this E1 reaction is the removal of the OH- group, which is known as the leaving group. Since the unimolecular rate-determining step is the slow step, this makes the reaction an E1 mechanism.1 The elimination of the alcohol leads to the ...
