S N 2 is a single-step reaction, so the diagram has only one curve. The products CH 3 OH and Br - are in lower energy than the reactants CH 3 Br and OH - , indicates that the overall reaction is exothermic and the products are more stable.

Energy profile diagram of E 2 reaction: Orientation and reactivity of E 2 reaction: In some cases, this reaction yields a single alkene but in other cases a mixture of alkenes are formed. For example, 2-bromopropane forms only propene whereas 2-bromobutane forms a mixture of 1-butene and 2-butene. Watch Complete videos @ An energy diagram for the single-step bimolecular E2 mechanism is shown on the right. We should be aware that the E2 transition state is less well defined than is that of S N 2 reactions. More bonds are being broken and formed, with the possibility of a continuum of states in which the extent of C-H and C-X bond-breaking and C=C bond-making varies. An energy diagram for the single-step bimolecular E2 mechanism is shown below. We should be aware that the E2 transition state is less well defined than is that of S N 2 reactions.

the E2 reaction increases. The increase in E2 reaction rate with increasing alkyl substitution can be rationalized in terms of transition state stability. In the transition state, the double bond is partially formed. Thus, the transition state for a more substituted alkene is lower in energy, reducing the activation energy for the
