An explanation of the molecular
An explanation of the molecular geometry for the I3 - ion (Triiodide Ion) including a description of the I3 - bond angles. The electron geometry for the Triiodide Ion is also provided.
The ideal bond angle for the Triiodide Ion is 180° since it has a Linear molecular geometry. Experimentally we would expect the bond angle to be approximately 180°.
To determine the molecular geometry, or shape for a compound like I3 -, 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 I3 - we would expect it to be Trigonal bipyramidal.
