Question:
Which compound has antifluorite structure?
Which compound has antifluorite structure?
Show Hint
The antifluorite structure is characteristic of compounds where the metal ions are smaller than the oxide ions, which results in a structure where oxygen ions form the framework.

- \( {MnO}_4\)
- \( {Na}_2 {O}\)
- \( {Na}_2 {O}_2\)
- \( {Li}_2 {O}_2\)

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The antifluorite structure is a type of crystal structure that is the inverse of the fluorite structure. In this structure, the anions (oxygen ions in this case) occupy the positions normally occupied by cations in the fluorite structure, and vice versa. Sodium oxide (\( {Na}_2 {O}\)) crystallizes in the antifluorite structure, where oxide ions ( \( {O}^{2-} \) )occupy the tetrahedral sites, and sodium ions (Na+) occupy the cubic sites.
