A compound is formed by two elements X and Y.
Atoms of 'Y' make ccp and those of element 'X' occupy tetrahedral voids.
The formula of the compound is:
- A XY
- B \(\text{X}_2\text{Y}\)
- C \(\text{XY}_2\)
- D \(\text{X}_2\text{Y}_3\)
Answer & Solution
Correct Answer
(B) \(\text{X}_2\text{Y}\)
Step-by-step Solution
Detailed explanation
Number of Y atoms (ccp) = 4 Number of tetrahedral voids = \( 2 \times 4 = 8 \) Number of X atoms = 8 Ratio X:Y = \( 8:4 = 2:1 \) Formula: \( \text{X}_2\text{Y} \)
