The S N 1 mechanism. A second model for a nucleophilic substitution reaction is called the ' dissociative', or ' SN1' mechanism: in this picture, the C-X bond breaks first, before the nucleophile approaches: This results in the formation of a carbocation: because the central carbon has only three bonds, it bears a formal charge of +1.Addition with 1,2- alkyl shift. Mechanism: Electrons from the C1-C2 π bond attack the hydrogen of HBr, expelling the bromide anion and leading to the formation of a carbocation (Step 1, arrows A and B).
