    AB crystallizes in a body centred cubic lattice with edge length 'a' equal to 387 pm. The distance between two oppositely charged ions in the lattice is:

    A) 335 pm

    B)        250 pm

    C) 200 pm

    D)        300 pm

    Correct Answer: A

    Solution :

    [a] For BCC lattice body diagonal \[=a\sqrt{3}.\] The distance between the two oppositely charged ions \[=\frac{a}{2}\sqrt{3}\] \[=\frac{387\times 1.732}{2}=335pm\]
