So, as per the SF2 lewis structure, the sulfur central atom is surrounded by 4 electron pairs(2 bond pairs + 2 lone pairs).

And the molecular geometry only considers the bond pair to predict the shape of the molecule. The electron geometry considers both bond pair and lone pair while predicting the geometry of the molecule. Why the molecular geometry of SF2 is bent but its electron geometry is tetrahedral? So, in the SF2 lewis structure, there are 2 bond pairs means 4 bonding electrons and 8 lone pairs (2 on central atom + 3 on each fluorine atom) are present. Lone pairs are those represented as dots in the lewis diagram that do not take part in the formation of bonds and are also called nonbonding electrons. A single bond has one bond pair means 2 bonding electrons. The bond angle of SF2 is around 98º as due to the lone pair on the sulfur central atom, both fluorine atom pushes down in the downward direction that contract the angle between them, and gives the approx F-S-F 98º angle.įAQ How many bonding pairs and lone pairs are present in the lewis structure of SF2?īonding pairs are the pair of electrons that are in a bond.

So, for a steric number of four, we get the Sp 3 hybridization on the sulfur atom in the SF2 molecule. ∴ Steric number of SF2 = (2 + 2) = 4 Steric number To change the symbol of an atom, double-click on. ∴ Steric number of SF2 = (Number of bonded atoms attached to sulfur + Lone pair on sulfur)Īs per the lewis structure of SF2, the sulfur atom is bonded with two fluorine atoms and it contains two lone pairs of electrons. Draw the molecule by placing atoms on the grid and connecting them with bonds. “Steric number is the addition of a total number of bonded atoms around a central atom and the lone pair present on it.” Let’s find the hybridization of SF2 through the steric number of its central atom. Also, the generic formula for SF2 is AX 2N 2 according to the VSEPR theory and its chart.
