In this video Paul Andersen explains how you can use Lewis Diagrams and VSEPR Models to make predictions about molecules. The Lewis diagrams are a two-dimensional representations of covalent bonds and the VSEPR models show how the...

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....

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...

The Valence Shell Electron Pair Repulsion (VSEPR) theory predicts molecular shapes by focusing on the repulsion between electron pairs surrounding a central atom. The main postulates include: Electron Pair Repulsion: Electron pairs...

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

BeCl₂ and BF₃ exhibit linear and trigonal planar geometries, respectively, as predicted by the VSEPR theory, minimizing electron pair repulsion

Struggling with VSEPR theory and molecular geometry? This video simplifies the concepts you need to master these essential chemistry topics. Learn how to draw Lewis structures with the correct geometry, understand bond angles, and...

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...

What's with all these shapes? Let's practice assigning hybridization, electron-domain geometry, and molecular geometry. Octahedral! Tetrahedral! Linear! Pyramids and see-saws and what not! Chemistry is fun, isn't it?

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...

In this video, we will determine the Lewis structure for the compound, CHCl3 (chloroform).<br/>

We are used to using a theory like VSEPR theory to predict molecular geometry, but unfortunately with coordination compounds, things are not so simple, because of those pesky d orbitals on the central metal atom. Crystal field theory is...

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...
