Electron-pair repulsion in chemistry affects molecular geometry and stability by positioning electron pairs to minimize repulsion.
Electron-pair repulsion around an atom is a concept in chemistry where electron pairs tend to orient themselves as far apart as possible to minimize repulsion due to like charges. This phenomenon leads to the prediction of molecular geometries based on the number of electron pairs around a central atom.
For example, in a molecule with two electron pairs, they arrange themselves in a linear geometry at 180° angle to minimize repulsion. This repulsion affects the shape and stability of molecules.
