Square pyramidal Explanation: In BrF5, bromine is the central atom with 7 valence electrons. It forms 5 bonds with fluorine atoms and has 1 lone pair. Total electron pairs = 6 ⇒ sp3d2 hybridisation, which gives an octahedral electron geometry, but due to one lone pair, the molecular shape becomes square pyramidal.
