A compound is compound by cation C and anion A. The anions hexagonal close packed (hcp) lattice and the cations occupy 75% of octahedral voids. The formula of the compound is

A

`C_2A_3`

B

`C_3A_2`

C

`C_3A_4`

D

`C_4A_3`

Text Solution

Verified by Experts

The correct Answer is:
C
No. of anions A per unit cell = 6
No. of octahedral sites = 6
No. of cations `C = (6 xx 75)/(100) = 9/2`
Formula `C_(9/2) A_6` or `C_3A_4`.
