PF5 has a trigonal bipyramidal molecular geometry, with the phosphorus atom at the center surrounded by five fluorine atoms. This geometry consists of three atoms in the same plane and two atoms above and below that plane.
SF6 does not have symmetrical geometry, while PF5 does. This is because SF6 has a trigonal bipyramidal molecular geometry, with six bonding pairs and no lone pairs, leading to an overall asymmetrical shape. In contrast, PF5 has a trigonal bipyramidal molecular geometry with five bonding pairs and one lone pair, resulting in a symmetrical shape due to the lone pair occupying one of the equatorial positions.
No, PF5 is not a dipole-dipole molecule. It has a trigonal bipyramidal geometry with fluorine atoms arranged symmetrically around the central phosphorus atom, resulting in a nonpolar molecule.
The molecular geometry of OSF4 is square pyramidal.
Tetrahedral
PF5 stands for phosphorus pentafluoride, which is a chemical compound consisting of one phosphorus atom bonded to five fluorine atoms. It is a highly reactive and toxic gas at room temperature.
