Energy level diagram of Sn2 reaction. In the Sn2 mechanism reaction, there is only a single step so a single curve is obtained for us. This graph shows that the intermediate has high energy and is less stable. The overall reaction is highly exothermic. The energy changes for the above reaction can be represented in the energy diagram shown in Fig. 7.1. 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. Oct 19, 2018 · SN2 Reaction follows second order rate kinetics. It forms a product via one transition state. Transition state is the state at which it posses. You may recall from general chemistry that it is often convenient to describe chemical reactions with energy diagrams. In an energy diagram.
