Molecular Geometry vs Electron Domain Geometry

[Michelle Argueta 1E]

What is the difference between the molecular geometry versus the electron domain geometry of a structure and how are they determined differently?

[Meg Yuan 1G]

Electron geometry is the arrangement of electron groups whereas molecular geometry just focuses on the arrangement of atoms based on the central atom and doesn’t include lone pairs.

Hi,

To determine the electron domain geometry you take into account both the position of bonding electron pairs and lone electron pairs. Instead, for the molecular geometry, you only consider the bonding electron pairs.

Hope this helps!
