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_4Y_4`

B

`X_2Y_3`

C

`X_2Y`

D

`X_3Y_4`

Text Solution

Verified by Experts

The correct Answer is:
A
From the given data, we have Number of Y atoms in a unit cell = 4
Number of X atoms in a unit cell ` = 8 xx 2/3 = 16/3`
From the above we get the formula of the compound as
`X_(16//3)Y_4` or `X_4 Y_3`
