Acidic strength of oxides of transition metals increases with increase in oxidation number. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/99317c6922907f7d785a0c6c3471272d-.jpeg" /> Hence acidic strength is of the order of underset text Basic MnO < Mn 3 O 4< underset text Amphoteric Mn 2 O 3< MnO 2< underset text Acidic Mn 2 O 7

Q. Arrange the oxides of manganese according to increasing acidic strength.

$M n O < M n_{3} O_{4} < M n_{2} O_{3} < M n O_{2} < M n_{2} O_{7}$

$M n_{2} O_{7} < M n O_{2} < M n_{2} O_{3} < M n_{3} O_{4} < M n O$

$M n O_{2} < M n_{2} O_{7} < M n_{3} O_{4} < M n_{2} O_{3} < M n O$

$M n_{3} O_{4} < M n_{2} O_{3} < M n_{2} O_{7} < M n O_{2} < M n O$

Acidic strength of oxides of transition metals increases with increase in oxidation number.

Hence acidic strength is of the order of
$Basic M n O < M n_{3} O_{4} < Amphoteric M n_{2} O_{3} < M n O_{2} < Acidic M n_{2} O_{7}$

Q. Arrange the oxides of manganese according to increasing acidic strength.

MnO<Mn3​O4​<Mn2​O3​<MnO2​<Mn2​O7​

Mn2​O7​<MnO2​<Mn2​O3​<Mn3​O4​<MnO

MnO2​<Mn2​O7​<Mn3​O4​<Mn2​O3​<MnO

Mn3​O4​<Mn2​O3​<Mn2​O7​<MnO2​<MnO

Acidic strength of oxides of transition metals increases with increase in oxidation number. Hence acidic strength is of the order of Basic MnO​<Mn3​O4​< Amphoteric Mn2​O3​​<MnO2​< Acidic Mn2​O7​​

$M n O < M n_{3} O_{4} < M n_{2} O_{3} < M n O_{2} < M n_{2} O_{7}$

$M n_{2} O_{7} < M n O_{2} < M n_{2} O_{3} < M n_{3} O_{4} < M n O$

$M n O_{2} < M n_{2} O_{7} < M n_{3} O_{4} < M n_{2} O_{3} < M n O$

$M n_{3} O_{4} < M n_{2} O_{3} < M n_{2} O_{7} < M n O_{2} < M n O$

Acidic strength of oxides of transition metals increases with increase in oxidation number.

Hence acidic strength is of the order of
$Basic M n O < M n_{3} O_{4} < Amphoteric M n_{2} O_{3} < M n O_{2} < Acidic M n_{2} O_{7}$
