Molecular bromine (Br2) on reaction with 3 moles of molecular fluorine (F2), it will produced 2 moles of BrF3.
BrF3 is interhalogen compound i.e.
trifluorobromide.
Br2(g)+3F2(9)→

2BrF3(9)

Trifluoro−bromide

e−=5e−i.e. sp3d hybridisation.
BrF3 contain 3‌Br−F−covalent bonds and 2 lone pairs.
BrF3 is sp3d hybridised molecule having T-shape.
Hence, total number of lone pairs at central halogen atom is 2 .
