WebE2 mechanism. The E2 mechanism, where E2 stands for bimolecular elimination, involves a one-step mechanism in which carbon-hydrogen and carbon-halogen bonds break to form a double bond (C=C Pi bond).. The specifics of the reaction are as follows: E2 is a single step elimination, with a single transition state.; It is typically undergone by primary substituted … WebIf you have a 3° carbon, the substitution reaction will be SN1. For 1° and 2° carbons, the substitution will be SN2. It is the strength of the base that determines the type of elimination. If you have a strong base, you will get E2 elimination. If you have a weak base, you will get E1 elimination from 3° substrates and probably no reaction ... WebJul 7, 2024 · On: July 7, 2024. Asked by: Torey Konopelski. Advertisement.
