Given below are two statements: Statement I: $\mathrm{Cr}^{2+}$ is oxidising and $\mathrm{Mn}^{3+}$ is…
- Both Statement I and Statement II are correct
- Both Statement I and Statement II are incorrect
- Statement I is correct but Statement II is incorrect
- Statement I is incorrect but Statement II is correct
Solution

Half filled $d$-orbital (more stable) Therefore, $\mathrm{Mn}^{3+}$ acts as an oxidising agent. $\mathrm{Sc}^{3+}$ - [Ar] All elements are paired making it diamagnetic. Hence $\mathrm{Sc}^{3+}$ compounds are repelled when placed in an external magnetic field.
