The Correct Option is A
Solution and Explanation
- **A) XeF\(_2\)**: Xenon difluoride (XeF\(_2\)) has 3 lone pairs on the central Xenon atom, thus it matches with **III**.
- **B) XeO\(_3\)**: Xenon trioxide (XeO\(_3\)) has 0 lone pairs on the central Xenon atom, hence it corresponds with **IV**.
- **C) XeF\(_4\)**: Xenon tetrafluoride (XeF\(_4\)) has 2 lone pairs on the central Xenon atom, matching with **I**.
- **D) PF\(_6\)**: PF\(_6\) has 1 lone pair on the central atom (Phosphorus), so it corresponds with **II**.
