A) \[FeO\]
B) \[F{{e}_{2}}{{O}_{3}}\]
C) \[F{{e}_{3}}{{O}_{4}}\]
D) All are possible
Correct Answer: B
Solution :
[b] There is one octahedral hole for each atom in hexagonal close packed arrangement. If the number of oxide ions \[({{O}^{2-}})\] per unit cell is 1, then the number of \[{{F}^{e3+}}\] ions \[=2/3\times \]octahedral holes \[=2/3\times 1=2/3.\] Thus, the formula of the compound \[F{{e}_{2/3}}{{O}_{1}}\] or \[F{{e}_{2}}{{O}_{3}}.\]You need to login to perform this action.
