Question
In a compound XY2O4, the oxide ions are arranged in CCP arrangement and cations X are present in octahedral voids. Cations Y are equally distributed between octahedral and tetrahedral voids. The fraction of the octahedral voids occupied is
Options
A.1/2
B.1/4
C.1/6
D.1/8
Solution
Octahedral voids in FCC = 4, but only one is occupied by ‘x’ and one by ‘y’.
