  • AX2E3 AX2E3
    Shape: Linear
    Steric Number: 5
    Lone Pairs: 3
    Polar/NonPolar: NonPolar
    Hybridization: sp3d
    Example: I3-

    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. All three equatorial orbitals contain lone pairs of electrons. The three atom molecule has a linear shape.
