On the other hand, an elimination reaction obeying the Hofmann rule generates a less substituted double bond in the product. However, these two types of elimination reactions proceed through the E2 mechanism.Answer and Explanation: The given alkene is produced as...

13 E2 Reactions (Mechanism) So, we need a better way to prepare alkenes from alkyl halides. There’s no way to do an E1 reaction on an alkyl halide without a nucleophile around, but strong non-nucleophilic bases exist. These can be used to promote E2 elimination reactions. eg. Why would...
E1 stands for unimolecular elimination. This means that the rate of the mechanism is only dependent on the concentration of the alkyl halide. This mechanism involves the formation of a carbocation intermediate after the halide has left the substrate. The base then attacks the hydrogen ...
