  • question_answer
    \[CsBr\] crystal has \[bcc\] structure. It has an edge length of \[4.3\,\,{AA}.\] The shortest interionic distance between \[C{{s}^{+}}\] and \[B{{r}^{-}}\]ions is     [IIT 1995]

    A) \[1.86\,\,{AA}\]             

    B) \[3.72\,\,{AA}\]

    C) \[4.3\,\,{AA}\]

    D) \[7.44\,\,{AA}\]

    Correct Answer: B

    Solution :

    Closest approach in bcc lattice \[=\frac{1}{2}\] of body diagonal \[=\frac{1}{2}\times \sqrt{3}a\]              \[=\frac{\sqrt{3}}{2}\times 4.3=3.72{AA}\].
