Identify the incorrect statement.

• A. \(Cr^{2+}(d^4 )\) is a stronger reducing agent than \(Fe^{2+}(d^6 ) \) in water.
• B. The transition metals and their compounds are known for their catalytic activity due to their ability to adopt multiple oxidation states and to form complexes.
• C. Interstitial compounds are those that are formed when small atoms like H, C or N are trapped inside the crystal lattices of metals
• D. The oxidation states of chromium in \(CrO_4^{2-}\) and \(Cr_2O_7^{2-}\)are not the same.

Answer 1

The Correct Option is D
