Energy diagram for sn1

A potential energy diagram for an S N1 reaction shows that the carbocation intermediate can be visualized as a kind ... SN1 reactions are nucleophilic substitutions, involving a nucleophile replacing a leaving group (just like SN2). However: SN1 reactions are unimolecular: the rate of this reaction depends only on the concentration of one reactant. SN1 reactions happen in two steps: 1. The leaving group leaves, and the substrate forms a carbocation intermediate. 2. Energy Diagrams: show change in energy during a reaction. When bonds break, there is an increase in energy. When bonds form, there is a decrease in energy.a. Transition state: cannot be isolated, just a path to get somewhere. Bonds are startign to break and/or form.b. Activation energy (ΔG+): difference in energy between reactants and ...

Figure 7.3 shows an energy diagram tracing the progress of a reaction that occurs by an S N 1 mechanism. The rate of the reaction reflects the activation energy required to form the carbocation intermediate. The activation energy required for step 2, addition of the nucleophile to the carbocation, is much smaller, so step 2 is very fast.
