Question

$M_2X$ 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

Answer 1

Answer: (D)

Correct answer is (d) Smaller cations occupy the position of $F^{-}$ ions and larger anions that of $C^{+ +}$ ions
