Does PF 5 have a dipole moment?

Yes, phosphorus trifluoride (PF₅) has a dipole moment. Although PF₅ has polar bonds due to the difference in electronegativity between phosphorus and fluorine, its symmetrical trigonal bipyramidal shape causes the dipoles to cancel each other out. As a result, PF₅ is a nonpolar molecule overall and does not have a net dipole moment.
