NOTES: This molecule is made up of 5 sp3d hybrid orbitals. Three orbitals are arranged around the equator of the molecule with bond angles of 120o. Two orbitals are arranged along the vertical axis at 90o from the equatorial orbitals. The shape of the orbitals is trigonal bipyramidal. One of the equatorial orbitals contains a lone pair of electrons. The four atoms are arranged around the central atom of the molecule in a distorted tetrahedral shape.
