Molecular Geometry of molecule is the three-dimensional arrangement of atoms in a molecule. It follows the Valence Shell Electron Pair Repulsion (VSEPR) theory which assumes that each atom in a molecule will be positioned so that there is minimal repulsion between the valence electron of that atom.
