A crystalline solid `XY_3` has ccp arrangement for its element Y. X occupies

A

66% of tetrahedral voids

B

33% of tetrahedral voids

C

66% of octahedral voids

D

33% of octahedral voids.

Text Solution

Verified by Experts

The correct Answer is:
D
As ratio of X and Y is 1:3 , X will occupy `1/3` rd of octahedral voids.
`:.` % of octahedral voids occupied by X `= 1/3 xx 100= 33.3%`
