Expert Answer:
The electronegative halogens inductively withdraw e-(s)from all the carbon atoms of the ring of the σ complex, and the o- , p- and m- benzonium ions each have a higher ∆H‡than that of the cation from benzene .The halogens have unshared electrons and can delocalize electron density to the o- and p-carbon atoms. Halogens are said to be Π-donating but σ - withdrawing.
