Step-by-step explanation:
The valence shell electron pair repulsion theory holds that the number of electron pairs on the outermost shell of the central atom in a molecule determines the shape of the molecule.
In accordance with this theory, the electron domain geometry of a molecule having 4 outer atoms and 2 lone pairs on the central atom is based on an octahedron. The molecular geometry of this molecule is square planar with a bond angle of 90 degrees.
