Nitrosyl bromide is the chemical compound with the chemical formula NOBr. It is a red gas with a condensing point just below room temperature.[1] It reacts with water.[1]
Nitrosyl bromide can be formed by the reversible reaction of nitric oxide with bromine.[2] This reaction is of interest as it is one of very few third-order homogeneous gas reactions. NOBr is prone to photodissociation at standard pressure and temperature.
- 2 NO + Br2 ⇌ 2 NOBr
Another way to make it is by way of nitric oxide reacting with potassium bromide.[1]
- 2NO2 + KBr → BrNO + KNO3
