Question

Fluorine is a better oxidising agent than chlorine although the its
electron gain enthalpy is less than Cl Why?

Priya G N · Accepted Answer

The oxidising capability of a
substance depends upon three factors: bond dissociation enthalpy,
electron gain enthalpy and hydration energy

Although electron gain enthalpy
of fluorine is less negative as compared to chlorine, fluorine is a
stronger oxidizing agent than chlorine, because of

i low enthalpy of dissociation of
F-F bond (158 8/ kJ mol-1) Due to its small size Fluorine's
hydration energy is very high hence better the oxidizing
power

ii high hydration enthalpy of F-
(515/ kJ mol-1) Fluorine has a greater electron-electron repulsion
among the lone pairs in the small sized F2 molecule where they are
much closer to each other than in case of Cl2, hence the enthalpy
of dissociation of F2 is lower than Cl2 which makes it better
oxidizing agent

Fluorine is a better oxidising agent than chlorine although the its electron gain enthalpy is less than Cl.Why?
