Question

Assertion (A): Mn^3+ is a much stronger oxidising agent than Fe^3+ in aqueous solution. Reason (R): Reduction of Mn^3+ gives the stable half-filled d^5 ion Mn^2+, whereas Fe^3+ (d^5) would be reduced to the less stable d^6 ion Fe^2+.

Accepted Answer

Both Assertion and Reason are true and the Reason is the correct explanation of the Assertion

Answer

Both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion

Answer

Assertion is true but Reason is false

Answer

Assertion is false but Reason is true

Assertion (A): $Mn X^{3 +}$ is a much stronger oxidising agent than $Fe X^{3 +}$ in aqueous solution. Reason (R): Reduction of $Mn X^{3 +}$ gives the stable half-filled $d^{5}$ ion $Mn X^{2 +}$ , whereas $Fe X^{3 +}$ ( $d^{5}$ ) would be reduced to the less stable $d^{6}$ ion $Fe X^{2 +}$ .
