In a compound, atoms of element Y form hexagonal closest packing and those of element X occupy `2/3` of tetrahedral voids. The formula of the compound will be
A. |
`X_3Y` |
B. |
`X_4Y_3` |
![]() |
C. |
`X_2Y_3` |
D. |
`X_2Y` |
Per every atom, there are two tetrahedral voids formula `=YX_(2(2/3))` ie `YX_(4/3)` or `X_4Y_3`
