Statement A : In close packing of spheres, a tetrahedral void is surrounded by four spheres whereas an octahedral void is surrounded by six spheres. Statement B : A tetrahedral void has a tetrahedral shape whereas an octahedral void has an octahedral shape.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
In tetrahedral void, void is surrounded by four spheres tetrahedrally while in octahedral void, void is surrounded by six spheres octahedrally.

In a closed packed structure
1 tetrahedral voids are bigger than octahedral
2 tetrahedral voids are smaller than octahedral
3 tetrahedral voids are equal in size as octahedral
4 None of the above
Explanation:
Radius ratio as for a tetrahedral void \(\left( {{{\rm{r}}_ + }/{{\rm{r}}_ - }} \right) = 0.2247\) to \(0.414.\) For an octahedral void \(\left( {{{\text{r}}_ + }/{{\text{r}}_ - }} \right) = 0.414\) to 0.732 . Therefore, in a closed packed structure, tetrahedral voids are smaller than octahedral voids.
