Nucleophilic Aromatic Substitution - Chemistry Steps

WebNucleophilic functional groups are those which have electron-rich atoms able to donate a pair of electrons to form a new covalent bond. In both laboratory and biological organic chemistry, the most relevant nucleophilic atoms are oxygen, nitrogen, and sulfur, and the most common nucleophilic functional groups are water, alcohols, phenols ... WebThe origin of this question is the comparison of nucleophilic aromatic substitution to S N 1 and S N 2 reactions where the breaking of the C-F bond occurs in the rate-determining step (S N 2 is usually one step). And since the C-F bond is stronger than the other C-halogen bonds, fluoride is the worst leaving group slowing down the substitution.
