The d- and f-Block Elements

Identify the incorrect statement.

A. $C r^{2 +}$ ( $d^{4}$ ) is a stronger reducing agent than $F e^{2 +}$ ( $d^{6}$ ) in water
B.Transition metals and their compounds are known for their catalytic activity due to their ability to adopt multiple oxidation states and form complexes
C.Interstitial compounds are those formed when small atoms like H, C or N are trapped inside the crystal lattices of metals
D.The oxidation states of chromium in $Cr O_{4}^{2 -}$ and $C r_{2} O_{7}^{2 -}$ are not the same✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
