A crystalline solid `XY_(3)` has ccp arrangement for its element Y. The element X occupies :

A

`66%` of tetrahedral holes

B

`33%` of tetrahedral holes

C

`66%` of octahedral holes

D

`33%` of octahedral holes

Text Solution

Verified by Experts

The correct Answer is:
D
The ratio of X and Y is `1:3`
`:.` X will occupy `1//3` rd of octahedral voids
`:.%` of octahedral voids occupied by X
`=1/3xx100=33.3%`
