BrF 3 is a fluorinating agent, but less reactive than ClF 3. [10] Already at -196 °C, it reacts with acetonitrile to give 1,1,1-trifluoroethane. [11] BrF 3 + CH 3 CN → CH 3 CF 3 + 1 ⁄ 2 Br 2 + 1 ⁄ 2 N 2. The liquid is conducting, owing to autoionisation: [6] 2 BrF 3 ⇌ BrF + 2 + BrF − 4. Fluoride salts dissolve readily in BrF 3 ...
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

A reaction of K[BrF 4 O] with HF. [3] Also, reactions of BrF 5 with IO 2 F, IOF 3, and I 2 O 5 produce BrO 2 F. [3] Hydrolysis of bromine pentafluoride at low temperatures: BrF 5 + 2 H 2 O → BrO 2 F + 4 HF
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
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]
