    The distance between an octahedral and tetrahedral void in fee lattice would be-

    A) \[\sqrt{3}\,a\]                

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

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

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

    Correct Answer: D

    Solution :

    Octahedral void present at the centre of cube and tetrahedral void is present at \[{{\left( \frac{1}{4} \right)}^{th}}\] of the distance along each body diagonal. \[\therefore \,\,\,\,\frac{\sqrt{3}a}{2}\,=\,\,2\,\,\times \] distance between octahedral and tetrahedral void.
