The lower the PKa of the Conjugate Acid , the better the leaving group, because then they can easily stabilize the developing negative Charge . Conversely, a strong Base is a poor leaving group. SN1 Reaction s prefer Halide ions as leaving groups. In Room Temperature Water , the sequence of lability is:
During the SN2 Nucleophilic Attack , a partial negative charge forms on the leaving group. During SN1 reactions, the leaving group an Ion izes and leaves. In the non-mechanistic transformations, ''leaving group'' is the actual substituent group present in the Substrate and product. See also
