  • a)
    XY2
  • b)
    X3Y2
  • c)
    XY
  • d)
    X2Y3
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Atoms of element X forms fcc lattice and those of the element Y occupy...
Number of atoms of X per unit cell = 4
Number of atoms Y per unit cell = (1/3) x 8
(∵ Number of tetrahedral voids = 2 x N)

Hence, Formula of the compound is X3, Y2

Atoms of element X forms fcc lattice and those of the element Y occupy...
Given information:
- Atoms of element X form fcc lattice
- Atoms of element Y occupy 1/3rd of the tetrahedral voids

To determine the formula of the compound formed between X and Y, we need to consider the ratio of X and Y atoms in the crystal lattice.

Explanation:
1. The fcc lattice consists of 4 atoms per unit cell. Each corner atom is shared by 8 unit cells, while each face-centered atom is shared by 2 unit cells. So, the total number of atoms in one unit cell can be calculated as:

Number of atoms = (8 × 1/8) + (6 × 1/2) = 4

2. The tetrahedral voids in an fcc lattice are located at the center of each tetrahedron formed by 4 atoms. The number of tetrahedral voids per unit cell can be calculated as:

Number of tetrahedral voids = 2 × Number of atoms

= 2 × 4 = 8

3. Since the atoms of element Y occupy 1/3rd of the tetrahedral voids, the number of Y atoms per unit cell can be calculated as:

Number of Y atoms = 1/3 × Number of tetrahedral voids

= 1/3 × 8 = 2.67 ≈ 3

4. The remaining voids are occupied by atoms of element X. Since each tetrahedral void is surrounded by 4 atoms, the number of X atoms per unit cell can be calculated as:

Number of X atoms = 4 - Number of Y atoms

= 4 - 3 = 1

5. Therefore, the ratio of X and Y atoms in the compound is X:Y = 1:3. The formula of the compound can be written as X3Y2, which is option B.

Conclusion:
The formula of the compound formed between element X and Y, where X atoms form an fcc lattice and Y atoms occupy 1/3rd of the tetrahedral voids, is X3Y2.
