Question

Arrange the oxides of manganese according to increasing acidic strength.

• A. $MnO<M{n}_3{O}_4$ < $M{n}_2{O}_3$ < $Mn{O}_2$< $M{n}_2{O}_7$
• B. $M{n}_2{O}_7$<$Mn{O}_2$<$M{n}_2{O}_3$ <$M{n}_3{O}_4$
• C. $Mn{O}_2$ < $M{n}_2{O}_7$ < $M{n}_3{O}_4$< $M{n}_2{O}_3<MnO$
• D. $M{n}_3{O}_4$ < $M{n}_2{O}_3$ < $M{n}_2{O}_7$ < $Mn{O}_2<MnO$

Answer 1

The correct option is A $MnO<M{n}_3{O}_4$ < $M{n}_2{O}_3$ < $Mn{O}_2$< $M{n}_2{O}_7$

${Mn}_2{O}_7>{MnO}_2>{Mn}_2{O}_3>{Mn}_3{O}_4>MnO$

$(+7)$ $(+4)$ $(+3)$ $(+2.66)$ $(+2)$

Arrange in decreasing order of acidic strength.
