Question:

Match List I with List II

List I List II
(A) Diamagnetic solid (I) \(CrO_2\)
(B) Ferromagnetic solid (II) \(Fe_3O_4\)
(C) Antiferromagnetic solid (III) \(NaCl\)
(D) Ferrimagnetic solid (IV) \(MnO\)

Choose the correct answer from the options given below:

Options:

(A)-(II), (B)-(IV), (C)-(I), (D)-(III)

(A) -(III), (B)-(I), (C)-(IV), (D)-(II)

(A) -(I), (B)-(III), (C)-(II), (D)-(IV)

(A) -(IV), (B)-(II), (C)-(I), (D)-(III)

Correct Answer:

(A) -(III), (B)-(I), (C)-(IV), (D)-(II)

Explanation:

The correct answer is option 2. (A) -(III), (B)-(I), (C)-(IV), (D)-(II).

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!
