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....

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: Predicting Molecular Shapes with Ease
VSEPR postulates state that the geometry of a molecule depends on the number and arrangement of bonding and lone electron pairs around the central atom

Limitations of VSEPR Theory
We've learned about VSEPR theory, and we know how to use it to predict molecular geometry for a variety of organic molecules. But in fact, there are situations where predictions made with VSEPR theory do not line up with experimental...

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...

Oxidation Bond Angle (NB)
What is the show Caesium and Iodine love watching together? CsI. The first video explains how to determine the bond angle of an oxidation. The second focuses on how to determine which are linear ions by using molecular geometry.

Molecular Structure and Geometry
While physics is known for the math connections, chemistry is know for geometric connections. The 11th video in the series discusses how to determine the molecular structure of bonded atoms in a 3-D plane using steric numbers.

VSEPR Examples
Ah is the element of surprise. It is also one of the few elements you won't encounter when doing VSEPR problems. The videos work many examples of VSEPR in various configurations and detail the angle degrees based on the number of atomic...
