Question
In an ionic solid AB2O4, the oxide ions form CCP. ‘A’ and ‘B’ are metal ions in which one is bivalent and another is trivalent (not necessarily in given order). If all the bivalent ions occupy octahedral holes and the trivalent ions occupy tetrahedral and octahedral voids in equal numbers, then the fraction of octahedral voids unoccupied is
Options
A.1/2
B.3/4
C.1/4
D.7/8
Solution
For electrical neutrality, A = bivalent and B = trivalent. Now, one octahedral void is occupied by ‘A’ and one by ‘B’.
