Hybrid Molecular Orbitals
more electron density in particular regions. The bonding in a molecule predicted from this model corresponds well with the measurable physical and chemical properties. We could use the symmetry-based method to construct molecular orbital diagrams for larger molecules as well, but this can get complicated for larger structures.

butane.chem.uiuc.eduWorksheet 13 - Molecular Shapes The shapes of molecules can be predicted from their Lewis structures by using the VSEPR (Valence Shell Electron Pair Repulsion) model, which states that electron pairs around a central atoms will assume a geometry that keeps them as far apart from each other as possible. This is illustrated by the drawings below.
