5 Major Electrophilic Aromatic Substitution Reactions

WitrynaActivating groups (the ones that stabilize the transition state and make the reaction faster) turn out to direct the electrophile to the ortho, para positions, while the deactivating groups put them in the meta position, except for the halogens! Halogens deactivate the aromatic ring, yet they direct the electrophile to the ortho and para … WitrynaSolution. Due to -I effect, it attract the electron toward itself and reduce the electron density on benzene so it deactivates the ring and the substitution takes place at meta position. Due to +R effect, it increase the electron density at ortho and para position by delocalisation of electrons. Resonance effect dominates over inductive effect. WitrynaWhen substitution does occur on an aromatic ring with deactivating group already attached, it tends to occur specifically at the meta position – deactivating groups are … citizens advice watford phone number
