NEET UG CHEMISTRY MCQ: REDOX REACTIONS

$\mathrm{C}{\mathrm{r}^{\mathrm{2 + }}}\,\mathrm{(}{\mathrm{d}^\mathrm{4}}\mathrm{)}$ is a stronger reducing agent than $\mathrm{F}{\mathrm{e}^{\mathrm{2 + }}}\,\mathrm{(}{\mathrm{d}^\mathrm{6}}\mathrm{)}$ in water.

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.

Interstitial compounds are those that are formed when small atoms like are trapped inside the crystal $\mathrm{H,}\,\,\mathrm{C}\,\,\mathrm{or}\,\,\mathrm{N}$
lattices of metals.

The oxidation states of chromium in $Cr\,O_4^{2 - }\,\,\mathrm{and}\,\,C{r_2}\,O_7^{2 - }$ are not the same.
