    Interionic distance for \[CsCl\]crystal is

    A) \[a\]                                     

    B) \[a/2\]

    C) \[\frac{\sqrt{3}}{4}a\]                                   

    D) \[\frac{2a}{\sqrt{3}}\]

    Correct Answer: C

    Solution :

    \[CsCl\] has body centred cubic arrangement For body centred cubic arrangement \[a=\frac{4r}{\sqrt{3}}\]                 \[\therefore \]  \[r=\frac{\sqrt{3}}{4}a\]where, r = interionic distance and a = edge length of cube.
