Question

The spinal structure (AB₂O₄) consists of an fcc array of O^2- ions in which the :

A.A cation occupies one-eighth of the tetrahedral holes and B cation occupies one-half of octahedral holes

B.A cation occupies one-fourth of the tetrahedral holes and the B cations the octahedral holes

C.A cation occupies one-eighth of the octahedral hole and the B cation the tetrahedral holes

D.A cation occupies one-fourth of the octahedral holes and the B cations the tetrahedral holes

A → × 8 = 1, B → 4 × = 2 and O^2- = 4 so formula of spinal = AB₂O₄
