D) None of these
Correct Answer: A
Solution :
[a] Oxygen forms fcc structure in which \[M{{g}^{2+}}\] occupies tetrahedral voids and \[A{{l}^{3+}}\] ions occupies octahedral void per unit cell. Total number of tetrahedral voids \[=2\times 4=8\] \[\therefore \] % tetrahedral void occupied \[=\frac{1}{8}\times 100\] \[=12.5%\]You need to login to perform this action.
