Question

The r / r  ratio of ZnS is 0.402. Which of the following is the incorrect statement?

(A) ZnS is 4 : 4 coordination compound.
(B) ZnS does not crystallize in rock salt type lattice because r / r is too small to avoid overlapping of S2-.
(C) Zn2+ ion is too small to fit precisely into the tetrahedral voids of S2- ions.
(D) Zn2+ ion is too large to fit into tetrahedral voids of S2- ions.
