    Chlorine trifluoride has 5 regions of electron density around the central chlorine atom (3 bonds and 2 lone pairs). These are arranged in a trigonal bipyramidal shape with a 175° F(axial)-Cl-F(axial) bond angle.
    In a ClF5 molecule, chlorine is the central atom featuring five single bonds with fluorine atoms. Since chlorine has 7 electrons in the valence shell, the remaining two electrons form a lone pair.

    Explanation:

    To determine the number of lone pairs of electrons on the central atom in interhalogen species, we need to look at the Lewis structure of each molecule or ion.

    ClF3:
    In ClF3, the central atom is Cl. It is surrounded by three F atoms and has one lone pair of electrons. Therefore, it does not have two lone pairs of electrons.

    ClF2-
    In ClF2-, the central atom is Cl. It is surrounded by two F atoms and has three lone pairs of electrons. Therefore, it has two lone pairs of electrons.

    CIF5:
    In CIF5, the central atom is Cl. It is surrounded by five F atoms and does not have any lone pairs of electrons. Therefore, it does not have two lone pairs of electrons.

    ICl2-
    In ICl2-, the central atom is I. It is surrounded by two Cl atoms and has three lone pairs of electrons. Therefore, it has two lone pairs of electrons.

    XeF2:
    In XeF2, the central atom is Xe. It is surrounded by two F atoms and has three lone pairs of electrons. Therefore, it has two lone pairs of electrons.

    Summary:
    Out of the given interhalogen species, only ClF2- and ICl2- have two lone pairs of electrons on the central atom. ClF3, CIF5, and XeF2 do not have two lone pairs of electrons on the central atom.
