## Question

### Solution

Correct option is

XY2

In zinc blende, Y- ions form ccp lattice and have two tetrahedral sits per atom or sphere.

For the formula XY, there are four tetrahedral sites for two atoms. Thus, the 25% of tetrahedral site, ie, one tetrahedral site is occupied by X+. Therefore, the formula of the compound is XY2.
