Скачать или смотреть BrF3 (Bromine trifluoride) Molecular Geometry, Bond Angles

An explanation of the molecular geometry for the BrF3 (Bromine trifluoride) including a description of the BrF3 bond angles. The electron geometry for the Bromine trifluoride is also provided.

The ideal bond angle for the Bromine trifluoride is 90° since it has a T-Shaped molecular geometry. Experimentally we would expect the bond angle to be approximately 86.2°.

To determine the molecular geometry, or shape for a compound like BrF3, 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 BrF3 we would expect it to be Trigonal bipryamidal.
