Answer

To solve the problem of matching the molecules from List 1 with their corresponding shapes from List 2, we will analyze each molecule step by step.

### Step-by-Step Solution:

1. **Identify the first molecule: SF₆**
- SF₆ has six fluorine atoms surrounding a central sulfur atom.
- The arrangement of these atoms leads to an **octahedral** geometry.
- **Match:** A) SF₆ → 3) octahedral

2. **Identify the second molecule: SF₄**
- SF₄ has four fluorine atoms and one lone pair on the sulfur atom.
- This results in a **distorted tetrahedral** shape (also known as a seesaw shape).
- **Match:** B) SF₄ → 5) distorted tetrahedral

3. **Identify the third molecule: SF₂**
- SF₂ has two fluorine atoms bonded to sulfur and two lone pairs on sulfur.
- This arrangement gives it an **angular** shape due to the repulsion of the lone pairs.
- **Match:** C) SF₂ → 1) angular

4. **Identify the fourth molecule: S₂F₂**
- S₂F₂ has two sulfur atoms and two fluorine atoms, leading to a structure that resembles an **open book**.
- **Match:** D) S₂F₂ → 2) open book

### Final Matches:
- A) SF₆ → 3) octahedral
- B) SF₄ → 5) distorted tetrahedral
- C) SF₂ → 1) angular
- D) S₂F₂ → 2) open book

### Conclusion:
The correct match is:
- A - 3
- B - 5
- C - 1
- D - 2

Thus, the final answer is **Option 4**: A-3, B-5, C-1, D-2.
