• question_answer Which of the following does not represent the correct order of the property indicated [CBSE PMT 1997] A) $S{{c}^{3+}}>C{{r}^{3+}}>F{{e}^{3+}}>M{{n}^{3+}}$ ionic radii B) $Sc<Ti<Cr<Mn$ Density C) $M{{n}^{2+}}>N{{i}^{2+}}<C{{o}^{2+}}<F{{e}^{2+}}$ ionic radii D) $FeO<CaO>MnO>CuO$ Basic nature

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