Vedclass · Answer

(A) The correct order for ionic radii of $M^{3+}$ ions is $Sc^{3+} > Cr^{3+} > Mn^{3+} > Fe^{3+}$.Option $A$ is incorrect because the given order $Sc^{3+} > Cr^{3+} > Fe^{3+} > Mn^{3+}$ does not match the actual trend.Option $B$ is correct as density generally increases across the $3d$ series.Option $C$ is correct as ionic radii decrease with increasing atomic number for $M^{2+}$ ions,though there are minor variations.Option $D$ is correct as basic nature depends on the oxidation state and electronegativity of the metal.

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