The Lewis structure of IF4- Iodine Tetrafluoride Ion involves a central iodine atom bonded to four fluorine atoms with one lone pair, totaling 36 valence electrons 7 from iodine, 7 from each of the four fluorines, plus 1 additional for the negative charge. This results in a square pyramidal geometry. The extra electron gives the ion a -1 charge, concentrated on the iodine. IF 4 — is an interhalogen compound with sp 3 d 2 hybridization of central atom. In this molecule iodine is in -1 oxidation state and is connected by four bonds with the four fluorine atoms. Actual structure of this molecule is square planar with a bond angle 90 0. Though the actual geometry of IF 4 — is octahedral. Lewis structure , introduced by Gilbert.

The Lewis electron-pair approach can be used to predict the number and types of bonds between the atoms in a substance, and it indicates which atoms have lone pairs of electrons. This approach gives no information about the actual arrangement of atoms in space, however. Keep in mind, however, that the VSEPR model, like any model, is a limited representation of reality; the model provides no information about bond lengths or the presence of multiple bonds. The VSEPR model can predict the structure of nearly any molecule or polyatomic ion in which the central atom is a nonmetal, as well as the structures of many molecules and polyatomic ions with a central metal atom. Instead, it is a counting procedure that accurately predicts the three-dimensional structures of a large number of compounds, which cannot be predicted using the Lewis electron-pair approach. We can use the VSEPR model to predict the geometry of most polyatomic molecules and ions by focusing on only the number of electron pairs around the central atom , ignoring all other valence electrons present. According to this model, valence electrons in the Lewis structure form groups , which may consist of a single bond, a double bond, a triple bond, a lone pair of electrons, or even a single unpaired electron, which in the VSEPR model is counted as a lone pair. Because electrons repel each other electrostatically, the most stable arrangement of electron groups i. Groups are positioned around the central atom in a way that produces the molecular structure with the lowest energy, as illustrated in Figure 9. Figure 9.
