well the title says it all. I’m studying for my chem exam and can’t pinpoint the difference of electron pair geometry and molecular structure. I know electron pair geometry is used for VSEPR theory, but what about the 2 are different?

Molecular structure differentiates between bonding pairs and lone pairs, while electron pair geometry does not.
For example, in water the oxygen has 2 covalent bonding pairs and 2 lone pairs, which corresponds to a “bent” molecular structure.
On the other hand, water has 4 electron pairs around it, so it has a tetrahedral electron pair geometry.
