VSEPR Theory and Molecular Geometry
Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary...

Shaping Molecules: Geometry of AB₄, AB₅, and AB₆ Explained
The geometry of molecules with the general formulas AB₄, AB₅, and AB₆ is determined by the Valence Shell Electron Pair Repulsion (VSEPR) theory, which helps predict molecular shapes based on the repulsion between electron pairs around...

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....

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...
