WebE2 Reaction In an E2 mechanism which refers to bimolecular elimination is basically a one-step mechanism. Here, the carbon-hydrogen and carbon-halogen bonds mostly break off to form a new double bond. However, in the E2 mechanism, a base is part of the rate-determining step and it has a huge influence on the mechanism. WebHere, I walk you through six practice problems on substitution and elimination, showing you my four-step method for determining reaction mechanisms.
