Molecular Geometry and AXE Notation

The video tutorial explains the molecular geometry of hypochlorous acid (HCl). It begins with an introduction to the molecule and its Lewis structure, followed by a discussion on the steric number and how lone pairs affect molecular geometry. The tutorial then explores the concept of bent molecular geometry and bond angles, emphasizing the impact of lone pairs. A 3D visualization of the molecule is provided to illustrate these concepts. Finally, the video introduces the AXE notation as a method to determine molecular geometry, concluding with a summary of the bent geometry of hypochlorous acid.
