    Which of the following is least soluble    [CPMT 1989]

    A)                 \[Be{{F}_{2}}\] 

    B)                 \[Sr{{F}_{2}}\]

    C)                 \[Ca{{F}_{2}}\] 

    D)                 \[Mg{{F}_{2}}\]

    Correct Answer: B

    Solution :

               The solubility order is :                 \[Be{{F}_{2}}>Mg{{F}_{2}}>\]\[Ca{{F}_{2}}>Sr{{F}_{2}}\] so \[Sr{{F}_{2}}\] is least soluble.
