    • A leaving group , LG, is
    • an atom (or a group of atoms) that is displaced as stable species taking
    • with it the bonding electrons. Typically the leaving group is an anion
    • (e.g. Cl-) or a neutral molecule (e.g. H2O).
    • The better the leaving group, the more likely it is to depart.

    • A "good" leaving group can be recognised as being the conjugate base
    • of a strong acid.
