    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.
