Question

Assertion (A): Mn^2+ does not get oxidised to Mn^3+ in aqueous solution, as E deg(Mn^3+/Mn^2+) = +1.5 V. Reason (R): Mn^2+ has the stable half-filled 3d^5 configuration.

Accepted Answer

Both A and R are true and R is the correct explanation of A

Answer

Both A and R are true but R is not the correct explanation of A

Answer

A is true but R is false

Answer

A is false but R is true

Assertion (A): $Mn X^{2 +}$ does not get oxidised to $Mn X^{3 +}$ in aqueous solution, as $E^{\circ} (Mn X^{3 +} / Mn X^{2 +}) = + 1.5 V$ . Reason (R): $Mn X^{2 +}$ has the stable half-filled $3 d^{5}$ configuration.
