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

    A)  \[LiF\]                                 

    B)  \[CsF\]

    C)  \[CsI\]                                 

    D) \[Lil\]

    Correct Answer: C

    Solution :

                    Ionic radii is the distance between the nucleus of an ion and a point upto which the nucleus has its influence on its electron cloud. The size of ions increases on moving from top to bottom in a group. Hence, the maximum distance between the centres of cations and anions is in\[CsI\]because\[C{{s}^{+}}\]is the largest cation and F is the largest anion.
