Sc3+> Cr3+> Fe3+> Mn3+ the correct order is Cr+3> Mn+3> Fe+3> Sc+3

Q. Which of the following does not represent the correct order of the property indicated?

$S c^{3 +} > C r^{3 +} > F e^{3 +} > M n^{3 +}$ ionic radii

$S c < T i < C r < M n$ Density

$M n^{2 +} > N i^{2 +} < C o^{2 +} < F e^{2 +}$ ionic radii

$F e O < C a O > M n O > C u O$ Basic nature

$S c^{3 +} > C r^{3 +} > F e^{3 +} > M n^{3 +}$ the correct order is $C r^{+ 3} > M n^{+ 3} > F e^{+ 3} > S c^{+ 3}$

Q. Which of the following does not represent the correct order of the property indicated?

Sc3+>Cr3+>Fe3+>Mn3+ ionic radii

Sc<Ti<Cr<Mn Density

Mn2+>Ni2+<Co2+<Fe2+ ionic radii

FeO<CaO>MnO>CuO Basic nature

Sc3+>Cr3+>Fe3+>Mn3+ the correct order is Cr+3>Mn+3>Fe+3>Sc+3

$S c^{3 +} > C r^{3 +} > F e^{3 +} > M n^{3 +}$ ionic radii

$S c < T i < C r < M n$ Density

$M n^{2 +} > N i^{2 +} < C o^{2 +} < F e^{2 +}$ ionic radii

$F e O < C a O > M n O > C u O$ Basic nature

$S c^{3 +} > C r^{3 +} > F e^{3 +} > M n^{3 +}$ the correct order is $C r^{+ 3} > M n^{+ 3} > F e^{+ 3} > S c^{+ 3}$
