What Is the Molecular Shape of BrF3?

TL;DR

The molecular shape of BrF3 is trigonal bipyramidal, resulting from the central bromine atom undergoing sp3 hybridization to form three unpaired electrons for bonding. In this structure, one fluorine atom occupies the equatorial position while the other two occupy the axial positions, and the presence of lone pairs influences the shape.
