Web8.1.1 E2 Mechanism. The E2 mechanism is the bimolecular elimination mechanism, and the reaction rate depends on the concentration of both the substrate and base. We will take the elimination reaction of 2-bromo-2-methylpropane as an example for discussion. It was mentioned earlier that HX is the side product of dehydrohalogenation, why there is ...
