Iron exhibits and oxidation states. Which of the following statements about iron is incorrect?
- AFerrous oxide is more basic in nature than the ferric oxide.
- BFerrous compounds are relatively more ionic than the corresponding ferric compounds
- CFerrous compounds are less volatile than the corresponding ferric compounds.
- DFerrous compounds are more easily hydrolysed than the corresponding ferric compounds.
Solution & Step-by-step Explanation
In Ferric () compounds, the charge is higher and the size of the ion is smaller compared to Ferrous (). According to Fajan's rules, the ion has a higher polarizing power, leading to more covalent character and easier hydrolysis. Therefore, Ferric compounds are more easily hydrolysed, making option D incorrect.
