Question

Match the crystalline solids in Column-I with packing arrangement in Column-II.

Answer 1

(A) $Ca{F}_2$ has a Fluorite structure. Cations have ccp arrangement and anions occupy all the tetrahedral voids.

(B) $NaCl$ has a Rock-Salt structure. Anions have ccp structure and cations occupy all the octahedral voids.

(C) $ZnS$ has a Zinc Blende or Sphelarite structure. Anions have ccp arrangement and cations occupy half of the total octahedral voids.

(D) $N{a}_{2}O$ has an Antifluorite structure. Anions have ccp arrangement and cations occupy all the tetrahedral voids.
