OF2 gemometry: sp3 hybridized atoms adopt a tetrahedral geometry. Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. According to VSEPR theory, five electron domains gives a parent geometry of trigonal bipyramidal. Source(s): My chemistry class. In chemistry, the term hybridization refers to combining two or more orbitals with different energies in a compound to give a hybrid orbital. The repulsion between these five pairs of valence electrons can be reduced by distributing the electrons across space. The first valence electron of the halogen occupies the s orbital; next three valence electrons go in px, py and pz orbital. Electron domain is used in VSEPR theory to determine the molecular geometry of a molecule. See more. PBr5 has Phosphorous as the central atom has eight electrons in its outer shell after forming the bond with neighbouring halogen atoms.
