A) NaCl type - \[C{{l}^{-}}\] ions in ccp structure. \[N{{a}^{+}}\] ions in half octahedral holes.
B) ZnS type - \[{{S}^{2-}}\] ions in ccp structure. \[Z{{n}^{2+}}\]ions in alternate tetrahedral voids.
C) \[Ca{{F}_{2}}\] type - \[C{{a}^{2+}}\] ions in ccp structure. \[{{F}^{-}}\] ions in all tetrahedral voids.
D) \[N{{a}_{2}}O\] type - \[{{O}^{2-}}\] ions in ccp structure. \[N{{a}^{+}}\] ions in all tetrahedral holes.
Correct Answer: A
Solution :
In NaCl type, \[C{{l}^{-}}\] ions form ccp structures while \[N{{a}^{+}}\] ions are present in all octahedral voids.
