Quizplus · Accepted Answer

In an E1 reaction, the first step is the formation of a carbocation (I) through the loss of a leaving group. Then, in the second step, a base attacks the carbocation and removes a proton, leading to the formation of a double bond (II). Attack of a nucleophile (III) and formation of a carboanion (IV) are not involved in E1 mechanism.
