Question

Match the following

• A. A-III, B-IV, C-I, D-II
• B. A-I, B-II, C-IV, D-III
• C. A-II, B-I, C-III, D-IV
• D. A-III, B-IV, C-II, D-I

Hint:

When matching molecules or ions to the number of lone pairs, consider the valence electron count of the central atom and how many are bonded versus lone pairs.

Answer 1

The Correct Option is A

- **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**.
