    An ionic compound is expected to have tetrahedral structure if \[{{r}_{+}}/{{r}_{-}}\] lies in the range of

    A)  \[0.414\]to\[0.732\],

    B)  \[0.225\]to \[0.414\]

    C)  0.155 to \[0.225\]

    D)  \[0.732\] to \[1\]

    Correct Answer: B

    Solution :

    Rodius ratio \[({{r}_{+}}/{{r}_{-}})\] Structure
    \[<0.155\] Linear
    \[0.155-0.225\] Planar triangular
    \[0.255-0.414\] Tetrahedral
    \[0.414-0.732\] Octahedral
    \[0.732-1\] bcc
