    1. Halogen elements have different electro-negativity.

    "The binary compounds formed by halogens amongst themselves are known as Inter-halogen compounds".

    2. The inter-halogen compounds may be regarded as the halide of the more

    electronegative halogen.

    Thus, since the electro positive character of halogens is

    in the order F < Cl < Br < I

    3. Since F has the least electropositive character, amongst inter-halogen compounds

    4. Inter-halogens can be grouped into four categories: AB, AB3, AB5, and AB7. Here

    A halogen atom is more electropositive and larger in size than B halogen atom.

    5. The oxidation state of atom A in AB, AB3, AB5, and AB7 molecules is equal to

    +1, + 3, + 5 and + 7 respectively.

    6. As the ratio between the radii of A and B atoms increases, the number of halogen

    atoms per molecule increases.
