Bromine mononitrate is an inorganic compound, derived from bromine and nitric acid with the chemical formula BrNO3. The compound is a yellow liquid, decomposes at temperatures above 0 °C.[1]

Synthesis

Bromine nitrate can be prepared by several methods:

1. Reaction of silver nitrate on an alcoholic solution of bromine:

Br2 + AgNO3 → BrNO3 + AgBr

2. Reaction of bromine chloride with chlorine nitrate at low temperatures:

BrCl + ClNO3 → BrNO3 + Cl2

Physical properties

Bromine mononitrate forms an unstable yellow liquid that decomposes at temperatures above 0 °C.

The molecule has the structure BrONO2.[2][3]

The compound is easily soluble in trichlorofluoromethane and carbon tetrachloride.

Applications

Bromine nitrate plays a role in tropospheric chemistry as it reacts with sulfuric acid.[4][5]
