The molecular geometry of SCl6 is Octahedral.
Explanation: Sulfur dichloride (SCl6) contains a sulfur atom surrounded by six chlorine atoms. To determine its geometry, we can use the VSEPR (Valence Shell Electron Pair Repulsion) theory. In SCl6, sulfur has six bonding pairs of electrons and no lone pairs. This arrangement leads to a symmetrical shape where all bond angles are equal, characteristic of an octahedral geometry.
When we visualize the spatial arrangement, the six chlorine atoms are positioned at the corners of an octahedron, with the sulfur atom at the center. This configuration minimizes the repulsion between the bonding electron pairs, resulting in the stable octahedral structure.
