Iron exhibits `+2 and +3` oxidation states. Which of the following statements 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 the corresponding ferric compounds.
C. Ferrous compounds are less volatile than the corresponding ferric compounds.
D. Ferrous compounds are more easily hydrolysed than the corresponding ferric compounds.

Answer

D

Explanation

(d) The statement is wrong. Actually, ferric compounds are more covalent than the ferrous compounds because `Fe^(3+)` ion has more polarising power than `Fe^(2+)` ion. Therefore, ferric compounds are more easily hydrolysed than ferrous compounds.
