Like ClF 3 and IF 3, the BrF 3 molecule is T-shaped and planar. In the VSEPR formalism, the bromine center is assigned two electron lone pairs.The distance from the bromine atom to each axial fluorine atom is 1.81 Å and to the equatorial fluorine atom is 1.72 Å.
Bromine monofluoride is a quite unstable interhalogen compound with the chemical formula BrF. It can be produced through the reaction of bromine trifluoride (or bromine pentafluoride) and bromine. Due to its lability, the compound can be detected but not isolated: [2] BrF 3 + Br 2 → 3 BrF BrF 5 + 2 Br 2 → 5 BrF Br 2(l) + F 2(g) → 2 BrF (g)
Refractory oxides tend to be only partially fluorinated, but here the derivatives KBrF 4 and BrF 2 SbF 6 remain reactive. Bromine trifluoride is a useful nonaqueous ionising solvent, since it readily dissociates to form BrF + 2 and BrF − 4 and thus conducts electricity. [43] Bromine pentafluoride (BrF 5) was first synthesised in 1930
ClF and BrF can both be produced by the reaction of a larger interhalogen, such as ClF 3 or BrF 3 and a diatomic molecule of the element lower in the periodic table. Among the hexatomic interhalogens, IF 5 has a higher boiling point (97 °C) than BrF 5 (40.5 °C), although both compounds are liquids at room temperature .
When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also known as the H-bond.
Bromine pentafluoride, Br F 5, is an interhalogen compound and a fluoride of bromine.It is a strong fluorinating agent.. BrF 5 finds use in oxygen isotope analysis. Laser ablation of solid silicates in the presence of BrF 5 releases O 2 for subsequent analysis. [2]

The fluorine–fluorine bond of the difluorine molecule is relatively weak when compared to the bonds of heavier dihalogen molecules. The bond energy is significantly weaker than those of Cl 2 or Br 2 molecules and similar to the easily cleaved oxygen–oxygen bonds of peroxides or nitrogen–nitrogen bonds of hydrazines. [8]
