Question
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
Options
A.CA
B.CA2
C.C2A3
D.C3A2
Solution
No. of A atoms = 6.
No. of C atoms = 6 ×
= 4.
∴ Formula = C4A6 or C2A3.
No. of C atoms = 6 ×
= 4.∴ Formula = C4A6 or C2A3.
