Spinel is an important class of oxides consisting of two types of metal ions with the oxide ions arranged in CCP pattern. The normal spinel has 1/ 8 of the tetrahedral holes occupied by one type of metal ion and 1/2 of the octahedral holes occupied by another type of metal ion. Such a spinel is formed by Zn2+, A13* and 02-with Zn2+ in the tetrahedral holes. If CCP arrangement of oxide ions remains undistorted in the presence of all the cations, formula of spinel and fraction of the packing fraction of crystal are respectively :
- a)ZnAl204 , 77%
- b)ZnAl2o4, 74%
- c)Zn2A104, 74%
- d)Zn3Al2O6, 74%

Formula of Spinel:
The formula of spinel can be determined by considering the occupancy of metal ions in the tetrahedral and octahedral holes. In this case, Zn2+ ions occupy the tetrahedral holes and Al3+ ions occupy the octahedral holes. The ratio of the number of tetrahedral sites to the number of octahedral sites is 1:2. Therefore, the formula of the spinel is ZnAl2O4.
Packing Fraction of Crystal:
The packing fraction of a crystal is the ratio of the volume occupied by the atoms or ions to the total volume of the unit cell. In this case, the crystal structure is cubic close-packed (CCP), which has a packing fraction of 0.74. This means that approximately 74% of the total volume of the unit cell is occupied by the atoms or ions.
Explanation of the Answer:
The given information states that the spinel consists of two types of metal ions with the oxide ions arranged in a cubic close-packed (CCP) pattern. It is also mentioned that the normal spinel has 1/8 of the tetrahedral holes occupied by one type of metal ion and 1/2 of the octahedral holes occupied by another type of metal ion.
From this information, we can determine that Zn2+ ions occupy the tetrahedral holes and Al3+ ions occupy the octahedral holes in the spinel structure.
The formula of the spinel can be determined by considering the occupancy of metal ions in the tetrahedral and octahedral holes. In this case, Zn2+ ions occupy 1/8 of the tetrahedral holes and Al3+ ions occupy 1/2 of the octahedral holes. The ratio of the number of tetrahedral sites to the number of octahedral sites is 1:2. Therefore, the formula of the spinel is ZnAl2O4.
The packing fraction of a crystal is the ratio of the volume occupied by the atoms or ions to the total volume of the unit cell. In this case, the crystal structure is cubic close-packed (CCP), which has a packing fraction of 0.74. This means that approximately 74% of the total volume of the unit cell is occupied by the atoms or ions.
Therefore, the correct answer is option 'A' which states that the formula of the spinel is ZnAl2O4 and the packing fraction of the crystal is 77%.
The formula of spinel can be determined by considering the occupancy of metal ions in the tetrahedral and octahedral holes. In this case, Zn2+ ions occupy the tetrahedral holes and Al3+ ions occupy the octahedral holes. The ratio of the number of tetrahedral sites to the number of octahedral sites is 1:2. Therefore, the formula of the spinel is ZnAl2O4.

The packing fraction of a crystal is the ratio of the volume occupied by the atoms or ions to the total volume of the unit cell. In this case, the crystal structure is cubic close-packed (CCP), which has a packing fraction of 0.74. This means that approximately 74% of the total volume of the unit cell is occupied by the atoms or ions.

It is also mentioned that the normal spinel has 1/8 of the tetrahedral holes occupied by one type of metal ion and 1/2 of the octahedral holes occupied by another type of metal ion.
From this information, we can determine that Zn2+ ions occupy the tetrahedral holes and Al3+ ions occupy the octahedral holes in the spinel structure.
The formula of the spinel can be determined by considering the occupancy of metal ions in the tetrahedral and octahedral holes. In this case, Zn2+ ions occupy 1/8 of the tetrahedral holes and Al3+ ions occupy 1/2 of the octahedral holes. The ratio of the number of tetrahedral sites to the number of octahedral sites is 1:2.

Therefore, the correct answer is option 'A' which states that the formula of the spinel is ZnAl2O4 and the packing fraction of the crystal is 77%.
