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. WebTherefore all halide anions except fluorine (HCl, HI, HBr) have good leaving groups because they can be heterolytically cleaved to accept the electron density of the sigma bond.
