On the basis of data given below, {E^{\circ}}_{Sc^{3+} \/ Sc^{2+}}=-0.37, {E^{\circ}}_{Mn^{3+} \/ Mn^{2+}}=+1.57 {E^{\circ}}_{Cr^{2+} \/ Cr}=-0.90, {E^{\circ}}_{Cr^{2+} \/ Cu}=0.34 Which of the following statements is incorrect?

Correct Answer is : Mn3+ is more stable than Mn2+.

Sc ^{3+} has good stability due of [ Ar ] 3 d^0 4 s^0 configuration.

Mn ^{3+} is more stable than Mn ^{2+}.

Cr ^{2+} is reducing in nature.

Copper does not give H _2 on reaction with dil. H _2 SO _4.
