Fluorine nitrate is an unstable derivative of nitric acid with the formula FNO
₃. It is shock-sensitive.[1] Due to its instability, it is often produced from chlorine nitrate as needed.

Synthesis and properties

Fluorine nitrate is formed when fluorine gas is bubbled through nitric acid or reacted with solid potassium nitrate:[2]

F₂ + HNO₃ → FNO₃ + HF

F₂ + KNO₃ → FNO₃ + KF

It decomposes in water to form oxygen gas, oxygen difluoride, hydrofluoric acid, and nitric acid.[1]

In fluorine nitrate, the oxygen atom bridging nitrogen and fluorine is in a rare oxidation state of 0 due to its electronegativity being lower than that of fluorine but higher than that of nitrogen.
