So the shape of BrF 5 molecule is square pyramidal. it exist as a diamer. PBr5 requires 5 bonds around the P. There are two nuclei about the central atom, so the molecular shape is bent, or V shaped, with an H–O–H angle that is even less than the H–N–H angles in NH 3, as we would expect because of the presence of two lone pairs of electrons on the central atom rather than one. As one electron goes to s orbital, three occupy the p orbital, and the last one enters the d orbitals of the central atom, the hybridization of Pbr5 is sp3d. aaesoph GO.
