It can be formed by reacting … WebEsters (-COOR) Halogens are also electron-withdrawing; the effect gets weaker going down the group. Electron-withdrawing and donating properties come from two different electronic effects that we need to understand: The mesomeric effect \, (M) is a group’s ability to delocalize electrons through resonance structures.
