Question

In the sphalerite (ZnS) structure, $S^{2-}$ ions form a face-centred cubic lattice. Then from the Comers, $Zn^{2+}$ ions are present on the body diagonals at

A

$\frac{1}{3}$ rd of the distance

B

$\frac{1}{4}$ th of the distance

C

$\frac{1}{6}$ th of the distance

D

$\frac{1}{8}$ th of the distance

Answer

$\frac{1}{4}$ th of the distance

Explanation

Solution

$Zn^{2+}$ ions are present at l/4th of the distance from the comer along each body diagonal (one on each body diagonal).
