E2 reactivity
WebJan 23, 2024 · E2 reactions are typically seen with secondary and tertiary alkyl halides, but a hindered base is necessary with a primary halide. The mechanism by which it occurs is a single step concerted reaction with one transition state.

WebThe rate law of the above E2 reaction follows: In the E2 reaction, a base removes a β -hydrogen, forms a double bond and kicks out the leaving group. The reaction occurs through a concerted mechanism and …
