    KF combines with HF to form \[KH{{F}_{2}}\]. The compound contains the species

    A) \[{{K}^{+}},{{F}^{-}}\]and \[{{H}^{+}}\]              

    B) \[{{K}^{+}},{{F}^{-}}\] and HF

    C) \[{{K}^{+}}\]and \[{{[H{{F}_{2}}]}^{-}}\]  

    D) \[{{[KHF]}^{+}}\]and \[{{F}_{2}}\]

    Correct Answer: C

    Solution :

    [c] Since F form H-bond \[{{[H{{F}_{2}}]}^{-}}\] exists. Therefore \[KH{{F}_{2}}\] gives \[{{K}^{+}}+H{{F}_{2}}^{-}\]
