Fluorine is the strongest oxidising agent because:-
1) 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.
2) High hydration enthalpy of F- ( 515/KJ mol-1 ). Fluo has a greater electron-electron repulsion among the lone pairs in the small sized F2 molecule where they are much closer to each other, hence the enthalpy of dissociation of Fluorine is lower which makes it strogest oxidizing agent.
