Question

MnO exhibits:

• A. Ferrimagnetism
• B. Antiferromagnetism
• C. Ferromagnetism
• D. Paramagnetism

Answer 1

The Correct Option is B

• MnO (Manganese(II) oxide) exhibits antiferromagnetism. In antiferromagnetic materials, the magnetic moments of adjacent ions or atoms align in opposite directions, leading to a net zero magnetization.
• In the case of MnO, the Mn²⁺ ions have a high-spin configuration and the electron spins in adjacent ions align in opposite directions, resulting in antiferromagnetic behavior at low temperatures.

Thus, MnO exhibits antiferromagnetism, making option (B) the correct answer.

Answer 2

MnO (Manganese(II) oxide) exhibits antiferromagnetism. In antiferromagnetic materials, the magnetic moments of atoms or ions are aligned in opposite directions, canceling each other out and resulting in no macroscopic magnetization at temperatures below the Néel temperature.
