A) \[{{X}_{4}}Y{{Z}_{2}}\]
B) \[{{X}_{4}}{{Y}_{2}}Z\]
C) \[X{{Y}_{2}}{{Z}_{4}}\]
D) \[{{X}_{2}}{{Y}_{4}}Z\]
Correct Answer: D
Solution :
[d] X is in f.c.c. lattice \[X=8\times \frac{1}{8}+6\times \frac{1}{2}=4\] T.H.O \[=4\times 2=8\] \[y=8\] O.H.V. = 4 \[Z=\frac{1}{2}\times 4=2\] \[{{X}_{4}}{{Y}_{8}}{{Z}_{2}}={{X}_{2}}{{Y}_{4}}Z\]
