Question

Element ‘B’ forms ccp structure and ‘A’ occupies half of the octahedral voids, while
oxygen atoms occupy all the tetrahedral voids. The structure of bimetallic oxide is

Answer 1

The structure of the bimetallic oxide is AB₂O₄.

Since B forms ccp structure, Z = 4 (⇒ B = 4)

Therefore, there are 4 octahedral voids and 8 tetrahedral voids.

Given, A occupies half of the octahedral voids. Therefore, A = 2

and, Oxygen atoms occupy all the tetrahedral voids. ⇒ Number of oxygen atoms = 8

A: B: O = 2:4:8 = 1: 2: 4

The structure of the compound is AB₂O₄.
