Transcript text: What is the electron geometry of $\mathrm{SF}_{6}$ ?
Solution
Solution Steps
Step 1: Determine the Number of Electron Groups
To determine the electron geometry of a molecule, we first need to identify the number of electron groups around the central atom. In the case of sulfur hexafluoride (\(\mathrm{SF}_6\)), sulfur (S) is the central atom. Each fluorine (F) atom forms a single bond with sulfur, resulting in six bonding pairs of electrons.
Step 2: Identify the Electron Geometry
The electron geometry is determined by the number of electron groups around the central atom. In \(\mathrm{SF}_6\), there are six electron groups (all bonding pairs). According to the VSEPR (Valence Shell Electron Pair Repulsion) theory, six electron groups around a central atom result in an octahedral electron geometry.
Final Answer
The electron geometry of \(\mathrm{SF}_6\) is \(\boxed{\text{octahedral}}\).
