There are two lone pairs of electrons on the central atom that do not participate in forming any bonds. The Lewis Structure of OF2 will have single bonds between O-F, with Oxygen atom in the centre. However, Oxygen atom is left with two pairs of nonbonding pairs of electrons. Every single bond will use up to 2 electrons.įluorine atoms will complete their octet by sharing electrons as now they will have eight electrons in their outer shell. Now each Fluorine atom forms a single bond with an Oxygen atom by sharing electrons. For example, Oxygen has six valence electrons, so draw six dots around the atom. Once you have placed all the atoms in this manner, start putting the valence electrons of the individual atom around them. SiH4 is the structural composition of silane/silicane. As Oxygen is less electronegative than the fluorine atom, it will be placed in the centre. Silane, also known as monosilane is the simplest of all the chemical compounds belonging to ‘silane’ groups which refer to binary silicon-hydrogen and organosilicon compounds having terminal hydrides. In OF2, the Oxygen atom will acquire the central position, and both the Fluorine atoms will go on the sides like this. However, there are many exceptions to this rule, but we always keep this rule in mind while drawing the Lewis structure for any molecule. Remember that all atoms follow the octet rule, which mentions that an atom that wants to attain a stable structure like inert gases must have eight valence electrons in its outer shell. Now that we know the total number of valence electrons for OF2, we can make the Lewis dot structure of OF2. So here we will first look at the Lewis Structure of Oxygen Difluoride and then check out other properties of this molecule.

This structure helps in determining other properties of the molecule. The Lewis structure of any molecule is a pictorial representation of the arrangement of valence electrons around individual atoms along with the bonds they form. Name of molecule Oxygen Difluoride ( O F 2 ) No of Valence Electrons in the molecule 20 Hybridization of O F 2 sp3 hybridization Bond Angles 109° 27′ Molecular Geometry of O F 2 Bentįor finding out the molecular geometry and hybridization of the molecule, it is vital first to know the Lewis Structure of OF2. It’s easy to understand the Lewis structure of this molecule as it has only two types of atoms in the molecule. This molecule’s chemical formula is OF2 as it contains one atom of Oxygen and two atoms of Fluorine. OF2 has a bent shape and a tetrahedral electron geometry. It has a linear molecular geometry and sp3 hybridization. The central oxygen atom has two lone pairs of electrons, and the bond angle of F-O-F is 109° 27. Oxygen Difluoride was first reported in 1929 while carrying out electrolysis of potassium chloride with hydrofluoric acid in the presence of water in little quantities. To summarize this blog, we can say that: In the Lewis Structure of OF2, both Fluorine atoms share a single bond with the Oxygen.
