PCl2F3 PClF4 PCl4F PCl3F2 PF5 (Select All That Apply.) Chem. Share 0. B. eines Moleküls). Thus the dipole moments cancel out to zero. (Assuming the molecule has a triangular bipyramidal structure) One could argue that it’d be nonpolar if the chlorine atoms were at the axial positions, and the fluorine was in the equatorial position, the molecule would be nonpolar. W. M. Tolles and W. D. Gwinn, J. Chem. The molecule XCl 2 has a dipole moment. Dipole Moment - Definition, Detailed Explanation and Formula R. P. Carter, Jr. and R. R. Holmes, Inorg. more electronegative element occupy axial position in sp3d hybridisation., and the reason lies in the structure only, in the case of PF2CL3 the dipole moment cancells out but in the case of PCL2F3, the dipole moment are not going to cancell out. This is somewhat of a rare molecule, but here is one similar: There are three possible structures for PCl 2 F 3 with phosphorus as the central atom.
