For example, the XeF 2 molecule has a steric number of five and a trigonal bipyramidal geometry. In IF5 the 5 F atoms are bonded with one I atom Hence number of sigma bonds is 5 and one lone pair if electron . The shapes of molecules can go a long way to telling us the bonding taking place in covalent molecules, but often the shapes do not coordinate with the ground state electron configuration of the central atom. Iodine Pentafluoride on Wikipedia. The five orbitals viz 1s, 3p, and 1d orbitals are free for hybridization. Earn Transferable Credit & Get your Degree. This is SP hybridization because our new hybrid orbitals came from one S orbital and one P orbital like that. The exponents on the subshells should add up to the number of bonds and lone pairs. 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. hybridization which results in octahedral geometry with two lone pairs occupy opposite positions. The iodine exhibits sp3d2 hybridization.
