Molecular Geometry and AXE Notation

This video tutorial explores the molecular geometry of the N-O-Cl compound. It begins with constructing the Lewis structure, highlighting the central position of nitrogen. The tutorial explains how to determine the steric number and use it to identify the molecular geometry as bent, with a bond angle of approximately 113 degrees. A visual representation of the molecule is provided, showing the effect of the lone pair on the geometry. The video also covers the electron geometry, which is trigonal planar, and explains the AXE notation for further understanding of the molecular shape.
