Visualizing Molecular Geometry With 3D Software
We've already learned about VSEPR theory, and how to use it to predict the shapes of various molecules. But we didn't cover all of the molecular geometries for certain hybridizations, and we didn't talk about bond angles, so let's do...

VSEPR Theory - lone electron pair influence
Bond Angle Distortion: Lone pairs reduce bond angles between bonding pairs. For example, in a molecule like NH₃ (ammonia), the ideal tetrahedral angle of 109.5° is compressed to around 107° due to the presence of a lone pair on nitrogen....
