The correct Answer is:
To solve the problem of matching the metal ions from List I with their corresponding magnetic moments from List II, we will analyze each compound step by step. ### Step-by-Step Solution: 1. **Identify the structure of XeF₄:** - Xenon (Xe) has 8 valence electrons. In XeF₄, 4 electrons are used to form bonds with 4 fluorine atoms, leaving 4 electrons (or 2 lone pairs). - The geometry of XeF₄ is square planar due to the presence of 2 lone pairs and 4 bonded fluorine atoms. - **Matching:** XeF₄ → Square planar (D) 2. **Identify the structure of XeF₆:** - In XeF₆, xenon uses 6 electrons to bond with 6 fluorine atoms, leaving 2 electrons (or 1 lone pair). - The presence of the lone pair distorts the geometry from an ideal octahedral shape to a distorted octahedral shape. - **Matching:** XeF₆ → Distorted octahedral (C) 3. **Identify the structure of XeO₃:** - In XeO₃, xenon uses 6 electrons to bond with 3 oxygen atoms (double bonds), leaving 2 electrons (or 1 lone pair). - The structure resembles that of ammonia (NH₃), which is pyramidal due to the lone pair. - **Matching:** XeO₃ → Pyramidal (A) 4. **Identify the structure of XeOF₂:** - In XeOF₂, xenon uses 4 electrons (2 for oxygen and 2 for fluorine), leaving 4 electrons (or 2 lone pairs). - The structure is T-shaped due to the arrangement of the lone pairs and the bonded atoms. - **Matching:** XeOF₂ → T-shape (B) ### Final Matching: - XeF₄ → D (Square planar) - XeF₆ → C (Distorted octahedral) - XeO₃ → A (Pyramidal) - XeOF₂ → B (T-shape) ### Answer: 1. XeF₄ → D 2. XeF₆ → C 3. XeO₃ → A 4. XeOF₂ → B Thus, the correct matching is: - (1) XeF₄ → (D) Square planar - (2) XeF₆ → (C) Distorted octahedral - (3) XeO₃ → (A) Pyramidal - (4) XeOF₂ → (B) T-shape
