Nucleophilic reaction definition. SN1 reactions are characterized by a two-step mechanism, in which the nucleophile attacks the carbocation intermediate formed after the departure of the leaving group. Definition Nucleophilic aromatic substitution is a chemical reaction where a nucleophile replaces a leaving group on an aromatic ring, typically one that has electron-withdrawing groups. An sp 3 -hybridized electrophile must have a leaving group (X) in order for the reaction to take place. This reaction is similar to the displacement reaction, where a more reactive element displaces a less reactive element in a solution. Definition Nucleophilic addition is a type of organic reaction where a nucleophile, an electron-rich species, adds to the carbon-carbon double bond of an electrophilic carbonyl compound, such as an aldehyde or a ketone. 3. In the S N i (internal nucleophilic substitution), a part of the leaving group must be able to attack the substrate detaching itself from the rest of the leaving group in the process. The bimolecular nucleophilic substitution reaction follows second-order kinetics; that is, the rate of the reaction depends on the concentration of two first-order reactants.
