WebThe electrophilic aromatic substitution (EAS) is a chemical reaction in which an atom attached to an aromatic system is replaced by an electrophile. Within the category of EAS reactions, there are a number of important chemical reactions …
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. WebMay 17, 2024 · A crossed double bond has sometimes been used to indicate unspecified double bond configuration or a mixture of configurations. This type of bond is not considered acceptable for general use, although it may still …
