Q.

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

  1. A

    A2B2O

  2. B

    AB2O4

  3. C

    A4B2O

  4. D

    A2BO4

Solution

Lattice formed by B(ccp) = 4

A = 50% of octahedral voids = 2

O = tetrahedral voids = 8

Formula = AB2O4.
