    Unlike other halogens, fluorine does not show higher oxidation states, because

    A)  it is highly electronegative

    B)  it has no d-orbitals

    C)  its atomic radius is very small

    D)  The \[{{F}^{-}}\] ion is stable and isoelectronic with  neon

    Correct Answer: B

    Solution :

    Oxidation state of F in all of its compounds is \[-1,\]while other halogen atoms show oxidation states from \[-1\] to \[+7\]. This is due to the absence of d-orbital in F atom.
