Beryllium Chloride Molecular Geometry

This video tutorial explores the molecular geometry of B2, specifically beryllium chloride. It begins with an introduction to the Leis structure, explaining how the two chlorine atoms push away from each other, resulting in a linear molecular geometry with a bond angle of 180°. The video provides a visualization of this geometry, highlighting the absence of lone pairs and the exception to the octet rule for beryllium. The tutorial concludes with an explanation of the AXE notation, reinforcing the linear geometry of B2.
