The correct Answer is:
To solve the matching question between List - I and List - II, we need to identify the correct pairs based on the properties of the materials mentioned. ### Step-by-Step Solution: 1. **Identify Antiferromagnetic Materials**: - Antiferromagnetic materials are those in which equal numbers of unpaired electrons align in opposite directions under an external magnetic field, resulting in a net magnetic moment of zero. - An example of an antiferromagnetic material is **MnO (Manganese Oxide)**. **Match**: A) Antiferromagnetic → 2) MnO 2. **Identify Covalent Crystals**: - Covalent crystals are characterized by a network of atoms connected by covalent bonds. A well-known example of a covalent crystal is **Diamond**, where each carbon atom is tetrahedrally bonded to four other carbon atoms. **Match**: B) Covalent crystal → 3) Diamond 3. **Identify Ferrimagnetic Materials**: - Ferrimagnetic materials have unequal numbers of unpaired electrons that align in opposite directions, resulting in a net magnetic moment that is non-zero but small. An example of a ferrimagnetic material is **ZnFe2O4 (Zinc Ferrite)**. **Match**: C) Ferrimagnetic → 1) ZnFe2O4 ### Final Matches: - A) Antiferromagnetic → 2) MnO - B) Covalent crystal → 3) Diamond - C) Ferrimagnetic → 1) ZnFe2O4 ### Conclusion: The correct matches are: - A → 2 - B → 3 - C → 1 Thus, the correct answer is **A-2, B-3, C-1**. ---
