How to find the molecular geometry for the OCl2 molecule (Dichlorine monoxide).
Molecular Visualization App: https://phet.colorado.edu/sims/html/molecule-shapes/latest/molecule-shapes_en.html
To determine the molecular geometry, or shape for a compound like OCl2, we complete the following steps:
Lewis Structure for OCl2: youtu.be/QwWQX0CyO3Y
🔹Draw the Lewis Structure for the compound.
🔹Predict how the atoms and lone pairs will spread out when they repel each other.
🔹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.
Note, if you are trying to find the electron geometry for OCl2 we would expect it to be Tetrahedral since we also consider the lone pairs in determining the geometry..
