The role of halogens in electrophilic aromatic substitution

WebIn short, the groups that donate electron density to the ring and make it electron-rich are activators. The ones that withdraw the electron density are deactivators. Activators increase the rate of electrophilic aromatic substitution and deactivators decrease it: There are two factors that determine if the group is electron donating or withdrawing.

WebOther 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. This may be called a –R effect, and this deactivates the ring towards EAS. WebTo get the chlorine into the 4-position (via intermediate B), you would have to react the chlorine with a ring with a methyl group on it. That means that to get the left-hand product, you would have to oxidise the methyl group first, …

WebThis is the electron-withdrawing inductive effect, also known as the -Ieffect. In short, alkyl groups tend to donate electrons, leading to the +Ieffect. Its experimental basis is the ionization constant. It is distinct from and often opposite to the mesomeric effect. Bond polarization[edit]

WebMar 7, 2024 · Nitrogen is an electron donating group, as it has +ve resonance effect (mesomeric).
