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

Options

A. `Sc^(3+)gtCr^(3+)gtFe^(3+)gtMn^(3+)` : ionic radii
B. `ScltTiltCrltMn` : Density
C. `Mn^(2+)gtNi^(2+)ltCo^(2+)ltFe^(2+)` : ionic radii
D. `FeOltCaOgtMnOgtCuO` : Basic nature

Answer

A

Explanation

`Sc^(3+)gtCr^(3+)gtFe^(3+)gtMg^(3+)` the correct order is `Cr^(+3)gtMn^(+3)gtFe^(+3)gtSc^(+3)`
