The nucleophilic substitution in haloarenes involves the nucleophilic substitution of a hydrogen atom in the aromatic ring by a nucleophile. The mechanism involves the concerted concerted mechanism, where the nucleophile attacks the electrophilic carbon atom in the aromatic ring, forming a new bond. This mechanism is typically favored by polar solvents and nucleophiles with lone pairs of electrons.
The nucleophilic substitution in haloarenes proceeds through an SN1 mechanism, where the nucleophile attacks the electrophilic carbon atom, and the leaving group is expelled simultaneously. The rate of nucleophilic substitution in haloarenes follows the Markovnikov principle, which states that the nucleophile attacks the carbon atom with the most hydrogen atoms.
Examples of nucleophilic substitution reactions in haloarenes include the reaction of haloarenes with sodium hydroxide in aqueous solution, which results in the substitution of the hydrogen atom on the carbon atom with hydroxide ion. Another example is the reaction of 2-chlorotoluene with hydroxide ion in aqueous solution, which results in the substitution of the hydrogen atom on the carbon atom with hydroxide ion
