WebApr 11, 2024 · Benzoxanthones, an oxygen-containing heterocyclic compound, have a wide range of reported activities like antiviral, ant diabetics, antibacterial, ... that the protonation energy was favored for the strong electron-withdrawing group but was lower for the weak electron-withdrawing groups or electron-donating groups. Weba year ago Are esters electron-withdrawing or electron-donating? In question 13, chapter 8 of Clayden, the answers say that replacing COOH with COOEt results in a greater electron-withdrawing effect. On the other hand, the book also says that COOEt can act as an electron-donor. I'm wondering, is this just a case of induction vs resonance?
WebSep 4, 2024 · Yes, OCH3 which belongs to the is the electron-withdrawing group (methoxy group). Is MeO an electron withdrawing group? b) -OCH3 (methoxy group) The methoxy group is electron withdrawing by the inductive effect of the oxygen atom, since the electronegativity of oxygen is 2.6. Is OMe donating or withdrawing? WebSep 26, 2024 · Get what activating and deactivating groups in fundamental chemistry?

WebApr 12, 2024 · And I believe that normally, carbonyl oxygens are electron withdrawing, at least when comparing the oxygen to the carbonyl carbon. I would think that rule would hold true here, and therefore, the ester oxygen would be electron donating towards the electron withdrawing carbonyl group.
