Question
In a face centerd lattice of X and Y, X atoms are present at the corners while Y atoms are at face centers. Then the formula of the compound would be if two atoms of X are missing from the corners :
Options
A.X4Y
B.X3Y4
C.XY4
D.X2Y4
Solution
for X, 6 × 
for Y, 6 ×
= 3
So X3/4 Y3 or X3 Y12 or XY4
for Y, 6 ×
So X3/4 Y3 or X3 Y12 or XY4
