Molecular Geometry of SO2

The video tutorial explains the molecular geometry of sulfur dioxide (SO2). It begins with the Lewis structure and uses the steric number to determine the bent molecular geometry, with a bond angle of approximately 119 degrees. A 3D visualization shows how the lone pair affects the geometry. The video concludes with the use of AXE notation to confirm the bent geometry of SO2.
