Vedclass · Answer

(D) The acidic or basic nature of transition metal oxides depends on the oxidation state of the metal. Generally,lower oxidation states of metals form basic oxides,while higher oxidation states form acidic or amphoteric oxides. $1$. $Mn_2O_7$ ($Mn$ in $+7$): Acidic oxide. $2$. $V_2O_3$ ($V$ in $+3$): Basic oxide. $3$. $V_2O_5$ ($V$ in $+5$): Amphoteric (predominantly acidic) oxide. $4$. $CrO$ ($Cr$ in $+2$): Basic oxide. $5$. $Cr_2O_3$ ($Cr$ in $+3$): Amphoteric oxide. Thus,$V_2O_3$ and $CrO$ are basic oxides. The correct option is $D$.

Which of the following are basic oxides among $Mn_2O_7 (I)$,$V_2O_3 (II)$,$V_2O_5 (III)$,$CrO (IV)$,and $Cr_2O_3 (V)$?
