Molecular Geometry of OF2

The video tutorial explains the molecular geometry of OF2 using VSEPR theory. It describes how lone pairs and atoms around the central oxygen atom repel each other, resulting in a bent molecular shape. The AXN notation is used to determine the geometry, and the bond angles are approximately 109.5 degrees. The tutorial concludes with a summary of the molecular geometry of OF2.
