WebThe most common leaving groups in nucleophilic substitution and elimination reactions are shown below: Notice that the stability of the leaving group has to do with the p K a value of the corresponding acid. The stronger the acid, the (weaker) more stable its conjugate base is, thus the better leaving group it is.
Webvery bad leaving group because Flourine forms very strong bonds. OH ion pKa of C.A. = 16. bad leaving group, strong base.

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.

The rate at which this mechanism occurs is second order kinetics, and depends on both the base and alkyl halide. A good leaving group is required because it is involved in the rate determining step.
WebYou can determine how "poor" of a leaving group it is by knowing the pKa of the acid related to the leaving group.
