The compound `AgF_2` is unstable compound . However , if formed , the compound acts as a very strong oxidising agent . Why ?

Explanation

In `AgF_(2)` oxidtion state of Ag is +2 which is highly unstable therefore it quickly accepts an electrons form the more stable +1 oxidation state `Ag^(2+)+E^(-)rarr Ag^(+)`
therefore `AgF_(2)` if formed will act as a strongoxidising agent
