Alternatively, electrophiles may also have polarizable π-bonds such as C=O or C=N. For example, in the picture at the beginning of this post we have a couple of electrophilic molecules. WebProtonation occurs first, creating a good leaving group, which is water in this case. Water then leaves the reaction, and the carbocation is formed. This second step is the rate determining step. The final step for this reaction will be the nucleophilic attack by chlorine. hamburger cupcakes ideas
