Webb1 juli 2024 · Is fluorobenzene or chlorobenzene more acidic? My bet goes to fluorobenzene. The reason is that fluorine is more electron-withdrawing. This is different than with HX, where the bond length is important. Here it is C-H in both cases. In the nitration, why fluorobenzene has less products in the ortho position than Clorobenzene?
