Iron exhibits +2 and +3 oxidation states. Which of the following about iron is incorrect?

Options

A. Ferrous oxide is more basic in nature than the ferric oxide.
B. Ferrous compounds are relatively more ionic than corresponding ferric compounds.
C. Ferrous compounds are less volatile than the corresponding ferric compounds.
D. Ferrous compounds are more easily hydrolyzed than corresponding ferric compounds.

Answer

D

Explanation

`FeO lt Fe_2 O_3` (Metals are more basic in lower oxidation state.) .
`FeO gt Fe_2 O_3`, (With increase in oxidation state covalent character increases.)
`FeO lt Fe_2 O_3` (Covalent compounds are more volatile.)
Because they are more electron deficient.
