WebApr 6, 2024 · Yes, the O C H 3 is an electron withdrawing group. The oxygen atom in the O C H 3 group is more electronegative than the carbon atom. Due to this reason, it will show the − I effect which is electron-withdrawing. An electron withdrawing group is a group which reduces electron density in a molecule through the carbon it is bonded to. WebElectron donating groups (EDG) add electron density to a system and tend to stabilize cations or electron poor systems. Conversely, EDG destabilize anions or electron rich systems.
