The compound `AgF_(2)` is unstable compound. However, if formed, the compound acts as a very strong oxidising agent. Why ?

Explanation

In `AgF_(2)`, oxidation state of `Ag` is `+2` which is very very unstable. Therefore. It quickly accepts an electron to form the more stable `+1` oxidation state
`Ag^(2+)+e^(Θ)rarr Ag^(o+)`
Therefore, `AgF_(2)`, if formed, will act as a strong oxidising agent.
