    In crystals which one of the following ionic compounds would you expect maximum distance between centres of cations and anions?

    A) \[LiF\]  

    B) \[CsF\] 

    C) \[CsI\] 

    D) \[LiI\]

    Correct Answer: C

    Solution :

    [c] As \[C{{s}^{+}}\] ion has larger size than \[L{{i}^{+}}\] and \[{{I}^{-}}\] has larger size than \[{{F}^{-}},\] therefore maximum distance between centres of cations and anions is in \[CsI\].
