fluorobromide
Fluorobromide is a hypothetical chemical compound with the formula BrF. It is not a stable compound and has not been definitively isolated or characterized. Theoretical calculations suggest that if it were to exist, it would likely be a highly reactive interhalogen. Interhalogens are compounds formed between two different halogen elements. Bromine and fluorine are both halogens, and their differing electronegativities could theoretically lead to the formation of a polar bond. However, fluorine is the most electronegative element, and it strongly prefers to bond with itself or other less electronegative elements. Bromine, being less electronegative than fluorine, would likely be the more electropositive atom in a BrF compound. Research into interhalogen compounds typically focuses on those that are stable and can be synthesized under laboratory conditions. The extreme reactivity predicted for fluorobromide makes its experimental investigation challenging. While some theoretical studies have explored its potential properties, its existence as a stable, isolable molecule remains speculative.
