So the hybridization state if I is sp3d2. * The electronic configuration of 'Be' in ground state is 1s2 2s2. Hybridization 1. Fluorine is more electronegative than iodine due to which dipole moment generates that makes the IF5 a polar molecule. The molecule has a bent shaped geometrical structure because of lone pair and bond pair repulsion as per VSEPR theory due to which there occurs an imbalance in charge distribution across the molecule. In case of sp 3 d, sp 3 d 2 and sp 3 d 3 hybridization state there is a common term sp 3 for which 4 sigma bonds are responsible. Therefore, it can obtain a set of 5sp 3 d hybrid orbitals directed to the 5 corners of a trigonal bipyramidal (VSEPR theory).The below diagram will help you depict easily.
