E1 Reaction Mechanism and E1 Practice Problems The energy diagram of the E1 mechanism demonstrates the loss of the leaving group as the slow step with the higher activation energy barrier: The dotted lines in the transition state indicate a partially broken C-Br bond. The Br being the more electronegative element is partially negatively charged and the carbon is partially positively charged. Energy Diagram For Sn2 In this diagram, there are really only three parts: the reagents, the transition state, and the products. The transition state is the point in the reaction with the highest energy level, and the difference in energy between the reagents and transition state is called the activation energy (often abbreviated as Ea). 8.5. Elimination reactions | Organic Chemistry 1: An open ... 8.5. Elimination reactions. Alkyl halides undergo elimination via two common mechanisms, known as E2 and E1, which show some similarities to S N 2 and S N 1, respectively. In E2, elimination shows a second order rate law, and occurs in a single concerted step (proton abstraction at C α occurring at the same time as Cβ-X bond cleavage).
