Question

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

• A. Ferrous oxide is more basic in nature than the ferric oxide
• B. Ferous 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 1

The correct option is D Ferrous compounds are more easily hydrolysed than the corresponding ferric compounds

Ferrous oxide is more basic in nature than ferric oxide. Ferrous compounds are relatively more ionic than the corresponding ferric compounds. Ferrous compounds are less volatile than the corresponding ferric compounds as ferrous compound is more ionic.

But ferric compounds are more easily hydrolyzed than the corresponding ferrous compounds due to their more positive charge.

So, option D is incorrect about iron.
