Answer & explanation
Correct answer: option 2
The correct answer is option 2. (A) -(III), (B)-(I), (C)-(IV), (D)-(II).
| List I | List II |
| (A) Diamagnetic solid | (III) \(NaCl\) |
| (B) Ferromagnetic solid | (I) \(CrO_2\) |
| (C) Antiferromagnetic solid | (IV) \(MnO\) |
| (D) Ferrimagnetic solid | (II) \(Fe_3O_4\) |
Let us look at the matching:
(A) Diamagnetic solid - Diamagnetic materials are repelled by magnetic fields. They have all paired electrons, resulting in no net magnetic moment. Example: \(NaCl\).
(B) Ferromagnetic solid - Ferromagnetic materials are strongly attracted to magnets and can be magnetized. They have unpaired electrons, resulting in a net magnetic moment. Example: \(CrO_2\).
(C) Antiferromagnetic solid - Antiferromagnetic materials have neighboring magnetic moments that align in opposite directions, resulting in overall zero magnetization. Example: \(Fe_3O_4\).
(D) Ferrimagnetic solid - Ferrimagnetic materials have magnetic moments aligned in opposite directions but with different magnitudes, resulting in a net magnetization. Example: \(MnO\).
So, indeed, the correct answer is option 2. (A) -(III), (B)-(I), (C)-(IV), (D)-(II). Thank you for the clarification!
