In a compound ,atoms of element Y from ccp lattice and those of element X occupy 2/3rd tetrahedral voids.The formula of the compound will be:A. `X_(3)Y_(4)`B. `X_(4)Y_(3)`C. `X_(2)Y_(4)`D. `X_(2)Y`

Answer» Correct Answer - B
Let number of atoms of Y used in packing `=n`
Number of tetrahedral voids `=2n`
Number of atoms of `X=(2)/(3)xx2n=(4)/(3)n`
`Y:X=n:(4)/(3)n=3:4`
Formula of compound `=X_(4)Y_(3)`
