WebElectron withdrawing group: A group, atom or molecule which can withdraw the electrons from the system or benzene ring is called electron withdrawing group. As methoxy group … WebAug 6, 2024 · In the presence of strong EDG & EWG, from resonance structures, the EDG donates electron density to ortho & para positions (those positions become more nucleophilic = activation) unless EWG is bonded to ortho/para, which withdraws the delocalized electrons. Therefore, in my case of meta-position nitro group, EDG trumps? …

WebFeb 28, 2024 · A = any substituent. E + = electrophile. If the relative yield of the ortho product and that of the para product are higher than that of the meta product, the substituent on the benzene ring in the monosubstituted benzene is called an ortho, para directing group. If the opposite is observed, the substituent is called a meta directing group. WebOrganic Chemistry.

Web* EDG: The electron-donating groups promote ortho & meta reduction. They deactivate the ring for overall reduction compared to the EWG. E.g. -R, -OR, -NR 2, -SR, PR 2, -CH 2 OH, -CHO, -C (O)R, CO 2 R etc., The -CHO, -C (O)R, CO 2 R act as electron donating groups because they are reduced to -CH 2 O - prior to the reduction of the ring.
