Solid State Question 32
Question: The $ {r _{+}}/{r _{-}} $ ratio of $ ZnS $ is 0.402. Pick out the incorrect statements from the following-
Options:
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 $ {{S}^{2-}} $ ions.
C) $ Z{{n}^{2+}} $ ion is too small to fit precisely into the octahedral voids of $ {{S}^{2-}} $ ions.
D) $ Z{{n}^{2+}} $ ion is too large to fit into the octahedral voids of $ {{S}^{2-}} $ ions.
