In a compound atoms of element `Y` form ccp lattice and those of element `X` occupy `2//3^(rd)` of tetrahedral voids. The formula of the compound will be

A

`X_(3)Y_(4)`

B

`X_(4)Y_(3)`

C

`X_(2)Y_(3)`

D

`X_(2)Y`

Text Solution

Verified by Experts

The correct Answer is:
B
In a cup array number of tetrahefral voids is swich the number of atom
`y:x: :1 [(2)/(3) xx 2] = 3:4`
`rArr X_(3)Y_(4)`
