Abstract
In the VIth group the situation with F → Cl → Br → I replacement in stabilization of free radical center appeared completely different compared with II-IV groups. Owing to the high electronegativity of HO-group and low thermodynamic stability of HO radical all halogens highly stabilize OX radical and perform it in the row F < Cl-Br < I which is explained by increase of PAZ effect in this direction. All halogens are suggested to stabilize other EX free radicals (E = S-Po) but essentially less compared with OX free radicals. The tendencies in stabilization/destabilization for Vth group free radicals appeared to be intermediate between those for IVth and VIth groups.
