If the anions (A) form hexagonal closest packing and cations (C) occupy only 2/3 octahedral voids in it. Then the general formula of the compound is

A

BA

B

`BA_(2)`

C

`B_(2)A_(3)`

D

`B_(3)A_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
In closest packing there is one octahedral hole per atom, the formula is `B_(2//3)A`.i.e., `B_(2)A_(3)`
