WebElectrophilic aromatic substitution (EAS) represents an important class of reactions taught in the undergraduate organic chemistry curriculum. The EAS reaction of benzene and its substituted derivatives is generally described as proceeding through a carbocation (arenium cation) intermediate, and the regiochemistry of the product is heavily influenced by the … WebJul 31, 2024 · This ion is formed from nitric acid and sulfuric acid according to the following equation: HNO 3 + 2H 2SO 4 ⇌ NO + 2 + H 3O + + 2HSO − 4 The nitronium ion attacks the aromatic ring to give first a nitrobenzenium ion and then an aromatic nitro compound:

WebThis is often called a +R (for resonance) effect, and this activates the ring towards EAS. Other groups contain an electronegative atom attached via a π-bond (e.g., C=O) that makes the group electron-withdrawing. These groups act as π-acceptors, drawing electron density away from the ring via resonance. birthmark scholarshipWebMar 24, 2024 · 18.4: Sulfonation of Benzene (an EAS Reaction) Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid.
