Among the halogen F2 is the strongest oxidising agent .Why?
Fluorine is a strongest oxidizing agent because
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 , hence the enthalpy of dissociation of Flourine is lower which makes it strongest oxidizing agent.
