Match List I with List II
| List I | List II |
| (A) Ferrimagnetic | (I) \(MnO\) |
| (B) Antiferromagnetic | (II) \(H_2O\) |
| (C) Ferromagnetic | (III) \(ZnFe_2O_4\) |
| (D) Diamagnetic | (IV) \(CrO_2\) |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-III, B-I, C-IV, D-II
(A) Ferrimagnetic — this matches (III) ZnFe2O4. \( \ce{ZnFe2O4} \) is a ferrite; its domain moments are unequal in the two directions, so a small net moment is left.
(B) Antiferromagnetic — this matches (I) MnO. In MnO equal numbers of domains point in opposite directions, so the moments cancel completely.
(C) Ferromagnetic — this matches (IV) CrO2. \( \ce{CrO2} \) is attracted very strongly by a magnetic field and can be permanently magnetised.
(D) Diamagnetic — this matches (II) H2O. All the electrons in water are paired, so it is weakly repelled by a magnetic field.
