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. WebElectrophilic aromatic substitution (EAS) reactions – the general picture. Although the delocalized pi electrons in aromatic rings are much less reactive than those in isolated or …
