Question

Assertion :$C{r}^{2+}$ is reducing and $M{n}^{3+}$ is oxidising. Reason: $C{r}^{2+}$ and $M{n}^{3+}$ have $d^4$ configuration.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

Since $Cr$ and $Mn$ are more stable in $+3$ an $+2$ oxidation state respectively. Hence, $C{r}^{+2}$ is reducing while $M{n}^{+3}$ is oxidizing.
