Скачать или смотреть SF6 (Sulfur hexafluoride) Molecular Geometry, Bond Angles

An explanation of the molecular geometry for the SF6 (Sulfur hexafluoride) including a description of the SF6 bond angles. The electron geometry for the Sulfur hexafluorideis also provided.

The bond angle for the Sulfur hexafluoride is 90° since it has a Octahedral molecular geometry.

To determine the molecular geometry, or shape for a compound like SF6, we complete the following steps:

1) Draw the Lewis Structure for the compound.
2) Predict how the atoms and lone pairs will spread out when the repel each other.
3) Use a chart based on steric number (like the one in the video) or use the AXN notation to find the molecular shape. This will be determined by the number of atoms and lone pairs attached to the central atom.

If you are trying to find the electron geometry for SF6 we would expect it to be Octahedral.
