Admittedly, my prior tutorial on MO theory was a little confusing, and had some errors. I wanted to make things right, so here's another one! This will clarify some of the basic concepts, and will also extend them to discuss a new...

Valence Bond (VB) theory explains how chemical bonds form through the overlap of atomic orbitals, where electron pairs are shared between atoms. The key concepts include: Atomic Orbital Overlap: Bonds form when atomic orbitals from...

The organic molecules that make up life on Earth are more than just the 2-D structures we’ve been drawing so far. Molecules have 3-D shapes that help us understand what they can do. In this episode of Crash Course Organic Chemistry,...

Alright, let's be real. Nobody understands molecular orbitals when they first take chemistry. You just pretend you do, and then in your next course you learn them a little better. And then a little better than that. And five years later...

It describes linear combination of atomic orbitals, conditions for combination of atomic orbitals, types of molecular orbitals and energy level diagram.

Bond-orbital theory, basic biomolecules and the construction of a person from the fundamental fields of physics, set to Ed Sheeran's "The Shape of You"

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...

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...

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...

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?

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....

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

In this video Paul Andersen explains how chemical reactions progress as bonds are broken and reformed reformed. He explains the difference between changes in state and changes in molecules. He discussed collision theory and explains...

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...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

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...

Improve your understanding of molecular properties with this lesson on the fascinating property of chirality. Your hands are the secret to understanding the strange similarity between two molecules that look almost exactly alike, but are...
