answer:The VSEPR (Valence Shell Electron Pair Repulsion) geometry of the molecule SF4 (sulfur tetrafluoride) can be determined by first analyzing its Lewis structure. Sulfur (S) has 6 valence electrons, and each fluorine (F) atom has 7 valence electrons. In SF4, sulfur forms four bonds with four fluorine atoms, using 4 of its valence electrons. The remaining 2 valence electrons on sulfur form a lone pair. Now, we can determine the VSEPR geometry by considering the number of bonding electron pairs and lone pairs around the central atom (S). In SF4, there are 4 bonding electron pairs and 1 lone pair around the sulfur atom. According to the VSEPR theory, the electron pairs will arrange themselves to minimize repulsion. In the case of SF4, the electron pairs form a trigonal bipyramidal arrangement, with the lone pair occupying one of the equatorial positions. This results in a molecular geometry known as "see-saw" or "distorted tetrahedron."

answer:The VSEPR geometry of a molecule of sulfur hexafluoride (SF6) is octahedral.

answer:The VSEPR (Valence Shell Electron Pair Repulsion) geometry of a carbon dioxide (CO2) molecule is linear. In CO2, the central carbon atom is bonded to two oxygen atoms through double bonds. There are no lone pairs on the central carbon atom, so the electron groups around the carbon atom are only the two double bonds. These electron groups repel each other and arrange themselves to be as far apart as possible, resulting in a linear geometry with a bond angle of 180 degrees.

answer:The VSEPR geometry of the methane (CH4) molecule is tetrahedral.
