Explanation 1: The sulfur tetrafluoride (SF4) is a polar molecule because, in SF4, the sulfur atom consists of one lone pair, due to which the shape of the molecules becomes asymmetric.The fluorine is more electronegative than sulfur. Molecular geometry can be determined by the number of bonds that a particular molecule has. Hence, SF4 has a trigonal bipyramidal molecular geometry. There are three lone pairs on each fluorine atom. So Cal/Vegas/AZ 818.639.2039. Molecular shape of sulfur tetrafluoride (SF4) : Molecular shape of bromochlorofluoromethane (CHBrClF) : Molecular shape of phosphine (PH3): - bent/v-shaped The shape of the SF4 molecule is tetrahedral. The equatorial fluorine atoms have 102° bond angles instead of the actual 120° angle. So in SF4 molecule we have bond pair =4 and lone pair =1 and sum is 5 the molecule due to lone pair will have d orbital and hybridization will be sp^3d and geometry will be trigonal bipyramidal. Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. As one can probably see, there is one sulfur atom in this compound and four fluorine atoms. Image courtesy:wikipedia.com Therefore SOF 4 is polar. A. Hence, the central atom, sulfur, will have one lone pair of electrons and four bonding pairs of electrons in the Lewis structure of SF4.

All the F-S-F bonds are 90 degrees, and it has no lone pairs. Step 3: Use VSEPR table to find the shape. All of them are in the hybridized orbitals. SF4 is the answer. What is the molecular geometry of BrF5? 2. Step 3: Use VSEPR table to find the shape. Lewis structure is a pictorial representation of the bonds and valence electrons in the molecule. Therefore SOF 4 is polar. Consequently, the molecule has two distinct types of F ligands, two axial and two equatorial. Sulfur tetrafluoride has 5 regions of electron density around the central sulfur atom (4 bonds and one lone pair). What is the electron geometry of CO2? One of the three equatorial positions is occupied by a nonbonding lone pair of electrons. The equatorial fluorine atoms have 102° bond angles instead of the actual 120 o angle. Moreover, Fluorine is more electronegative than Sulfur due to which the overall charge distribution of a molecule is uneven resulting in a polar molecule and give 0.632 D dipole moment.
