What does the vseper theory describe?

Answer 1

VSEPR theory, or Valence Shell Electron Pair Repulsion theory, describes the spatial arrangement of atoms in a molecule based on the repulsion between electron pairs in the valence shell of the central atom. It posits that electron pairs, whether bonding or lone pairs, will arrange themselves as far apart as possible to minimize repulsion, leading to specific molecular geometries. This theory helps predict the shapes of molecules, such as linear, trigonal planar, tetrahedral, and octahedral, based on the number of electron pairs around the central atom.
