Based on standard chemical analysis of the series transition metal oxides, which of the following co — d and f Block Elements Chemistry Question

💡 Solution & Explanation

The acidic character of a transition metal oxide directly correlates with the oxidation state of the metal. Extremely high oxidation states yield covalent, acidic oxides. $CrO_3$ ($Cr$ is $+6$), $Mn_2O_7$ ($Mn$ is $+7$), and $V_2O_5$ ($V$ is $+5$) are all classically acidic. $MnO$, having $Mn$ in a low $+2$ oxidation state, is structurally ionic and basic.
