Question

M₂X has anti fluorite structure. In such structure
(a) X⁻⁻ ions occupy all the 8 octahedral voids
(b) Each X⁻⁻ is surrounded by 4 M⁺ in tetrahedral arrangement
(c) Larger cations occupy the position of F⁻ions
and smaller anions that of C⁺⁺ ions
(d) Smaller cations occupy the position of F⁻ions
and larger anions that of C⁺⁺ ions
