WebSN1 means the leaving group (Br) leaves to form the C+! If you can form a more stable carbocation, you will always form one. When you draw out the mechanism, you see that the initial secondary carbocation—the “void”—impels the double bond to move. Doing so creates a tertiary carbocation. pho in bethesdaWebS N 1 reactions. In tertiary halogenoalkanes the carbon that is attached to the halogen is bonded to three alkyl groups.
