Bromine trifluoride physical properties

The physical properties of the interhalogens are intermediate between those of their parent halogens. Trends in the chemistry of the interhalogen fluorides can be related to the decrease in bond dissociation energy as the central halogen atom becomes heavier. The fluorides of the heavier halogens are all very reactive bromine trifluoride gas is so reactive that even asbestos burns in it. 

Bromine trifluoride is a pale yellow liquid at 298 K selected physical properties are given in Table 8.8 and the compound is discussed again in Section 16.7. Bromine trifluoride is an extremely powerful fluorinating agent and fluorinates essentially every species that dissolves in it. However, massive quartz is kinetically stable towards Brp3 and the solvent can be handled in quartz vessels. Alternatively, metal (e.g. Ni) containers can be used the metal surface becomes protected by a thin layer of metal fluoride.
