    If the value of ionic radius ratio \[\left( \frac{{{r}_{c}}}{{{r}_{a}}} \right)\] is 0.52 in an ionic compound, the geometrical arrangement of ions in crystal is

    A)                 Tetrahedral       

    B)                 Planar

    C)                 Octahedral         

    D)                 Pyramidal

    Correct Answer: C

    Solution :

                    The value of ionic radius ratio is 0.52 which is between \[0.414-0.732,\] then the geometrical arrangement of ions in crystal is octahedral.
