Molecular Geometry and AXE Notation

The video tutorial explains the molecular geometry of OC2, also known as Cl2O. It discusses the Lewis structure, highlighting the presence of two chlorine atoms and an oxygen atom in the center. The tutorial emphasizes the role of lone pairs in determining the bent molecular geometry. It uses 3D visualization to show how lone pairs and atoms repel each other, resulting in the bent shape. The video also introduces the AXE notation to describe the molecular shape and concludes with a reference to further learning resources.
