WebEffects of Leaving Group Since leaving group removal is involved in the rate-determining step of the S N 1 mechanism, reaction rates increase with a good leaving group. A good leaving group can stabilize the electron pair it obtains after the breaking of the C-Leaving Group bond faster. WebReactivity and stability are two opposing concepts. The more stable a molecule is, the less it wants to react. ... So we have these two competing effects, induction versus resonance. And whichever one is going to win- we can think about this balance for helping us to determine the reactivity of our carboxylic acid derivatives. So we start with ...
