The oxide that shows magnetic property is :

Question

Choose the correct statements in respect of hydrides of group 15.
(A) Reducing power increases down the group
(B) Basic nature increases down the group
(C) Stability decreases down the group
(D) Boiling point decreases regularly down the group.

Answer 1

To determine which oxide shows magnetic properties among the given options, let's explore each one:

SiO₂ (Silicon Dioxide): This oxide is non-magnetic. It's a covalent compound found in sand and quartz and does not exhibit magnetic properties.
Mn₃O₄ (Manganese(II,III) Oxide): This is a mixed-valence compound, consisting of both Mn²⁺ and Mn³⁺ ions. The presence of unpaired electrons in manganese ions gives rise to magnetic properties.
MgO (Magnesium Oxide): This is an ionic compound formed by Mg²⁺ and O^2- ions. It is not magnetic as there are no unpaired electrons.
Na₂O (Sodium Oxide): This is another ionic compound consisting of Na⁺ and O^2- ions, which also does not exhibit magnetic properties as it lacks unpaired electrons.

Given the analysis, Mn₃O₄ is the only oxide that shows magnetic properties due to the presence of unpaired electrons. These unpaired electrons lead to magnetic moments, which are absent in the other listed compounds.

Conclusion: The correct answer is Mn₃O₄, as it exhibits magnetic properties.
