WebIncrease SN2 reactivity The Leaving Group (LG) • The best leaving groups are those that can stabilize the negative charge in the transition state. The reason leaving ability depends on basicity; the weaker the basicity, the better of its leaving group. • Example: The iodide ion is the weakest base WebKeep in mind that leaving groups exist on a spectrum of good versus bad; it's not an either/or situation. So something like an iodide anion is considered a good leaving group, as is a chloride anion, but the iodide is a … Web18 Jan 2024 · So another key to identifying where a nucleophilic substitution or elimination reaction will occur is to examine the carbon attached to the good leaving group .
