Among the following metal oxides, which one exhibits antiferromagnetic behavior?

1. MnO2
2. TiO2
3. VO2
4. CrO2

Correct answer: MnO2

Solution

MnO2 exhibits antiferromagnetic behavior due to its crystal structure and the presence of manganese ions, which have unpaired electrons that align oppositely in neighboring ions, resulting in a net magnetic moment of zero.
