Steric number = Number of bonds on central atom + Number of lone pairs on the central atom.Īnd as we have seen there are two bonds and two lone pairs of electrons on the sulfur atom. By that, we can deduce the hybridization of the compound, which comes as sp3.Īnother way of finding the hybridization of SF2 is by calculating the steric number of SF2, which we can find by the following equation. When we consider the electronic configuration of SF2 then it comes to 3s2 3Px2 3Py1 3Pz1. These configurations are decided on the basis of the number of electrons these elements have. Similarly, the electronic configuration of Fluorine is 1s2 2s2 2p5. First, the electrons are filled in 1s, then in 2s, and so on. The electronic configuration of Sulfur is 1s2 2s2 2p6 3s2 3p4. Hybridization is related to the mixing of orbitals that are at different energies. The bond formation in SF2 is a single bond which means it is a sigma bond. In the case of SF2, you can look at the below-given diagram to understand how the electrons are placed in different energy orbitals. In the second energy level, 8 electrons can fit. In the first energy level, 2 electrons can fit. See the below-given chart to know about the capacity of each energy level. There are four energy levels and each energy level can accommodate a different number of electrons. Hybridization is the concept of knowing and identifying that how many electrons are there in the different energy orbital. Now, let us move to what is the hybridization of SF2. This explains the Lewis structure of SF2, how the bonds are made, and how many lone pairs of electrons are there. Thus, there are two lone pairs of electrons on Sulfur that did not get to participate in bond formation.Īnd there are three lone pairs of electrons on each Fluorine atom, which makes it a total of six pairs of lone electrons for the SF2 compound as a whole. Out of these 16 valence electrons, 4 are of sulfur and 6 are of each Fluorine atom. So, after two bonds are formed, out of 20 valence electrons only 16 valence electrons are left. You can understand and make Lewis’s structure when you know how many electrons are shared and how many electrons are left as lone pairs of electrons. One pair of electron sharing means that only a single bond is formed between Sulfur and two atoms of Fluorine each. Thus, the two atoms of Fluorine share one electron each with two atoms of Sulfur. Here Fluorine needs only one electron to complete its octet. This is because it is less electronegative than the other atom of the compound which is Fluorine.Įvery atom needs to fill its outer shell to become stable. Now, these valence electrons take their place around the central atom. Therefore, the total number of valence electrons in Sulfur Difluoride is 20. Thus, The total number of valence electrons = Valence electrons of Sulfur + Valence electrons of 2 Fluorine atoms There are in total 2 atoms of Fluorine in this compound. And, the valence electrons of Fluorine are 7 in number. Valence electrons of Sulfur are 6 in number. It is important to look at what the Lewis Structure of SF2 is so that we can move ahead and look at other aspects of it.įirst, we will have to calculate the total number of valence electrons in this compound. Lewis Structure is nothing but an arrangement of valence electrons between different atoms. Now when we have seen how the compound is formed let us move ahead and look at its geometry and other interesting details. However, under acute circumstances, the compound can cause respiratory irritation. The compound is not hazardous in nature and does not require special handling and storage. This compound is formed when sulfur dichloride reacts at low pressure with either potassium fluoride or mercury (||) fluoride.Īnother method of formation of Sulfur DiFluoride is when oxygen difluoride reacts with hydrogen sulfide. With a molar mass of 70.062 g/mol, this compound is made up of one Sulfur atom and two Fluoride atoms. Sulfur Fluoride is a highly unstable inorganic compound.
