Is BrF5 Polar?
Last Updated Mar 31, 2020 3:37:55 PM ET
BrF5 or bromine pentafluoride is a polar molecule. The molecular geometry of BrF5 is square pyramidal with an asymmetric charge distribution. The molecule has a central bromine atom that is surrounded by five fluorides and a lone pair of electrons.
According to Tutor Homework, the polarity is best found by first drawing the Lewis dot structure for BrF5. The electron geometry is octahedral, and the hybridization is sp3d2. Next, draw the 3-dimensional structure for BrF5 using VSEPR rules. Be sure to draw in the lone pair of electrons. The asymmetrical charge distribution can be seen, concluding that bromine pentafluoride is a polar molecule.
