F2 is a very strong oxidising agent due to which it displaces oxygen from water.
Fluorine as a strong oxidising agent
When a halogen has low energy of dissociation, a high electron affinity, and higher hydration of its ion, it will have high oxidizing power.
- Fluorine has although low electron affinity than Chlorine but low dissociation energy and have high hydration energy of its ion, therefore Fluorine is the strongest oxidizing agent.
- Fluorine is more electronegative therefore it can attract a shared pair of an electron more easily and strongly than other halogens.
- Fluorine is the best oxidising agent because it has a higher reduction potential (more ability to lose the electrons).
- The tendency of losing electrons assigned to Flourine is due to its more electronegativity of it.
Hence fluorine acts as a strong oxidising agent.
