Options

A. `SbF_(5)^(2-), XeF_(5)^(-), IF_(5)`
B. `SF_(4), XeOF_(4), PCl_(4)^(+)`
C. `SF_(6), PF_(6)^(-), IOF_(5)`
D. `COCl_(2), SOCl_(2), XeOF_(2)`

Answer

To determine which of the given molecules have the same geometry, we need to analyze the molecular geometry of each option provided. Here’s a step-by-step breakdown of the analysis:

### Step 1: Analyze the first set of molecules
1. **SbF5**:
- Antimony (Sb) is the central atom with five fluorine (F) atoms surrounding it.
- The molecular geometry is **square pyramidal** due to the presence of one lone pair on the antimony atom.

2. **XeF5⁻**:
- Xenon (Xe) is the central atom with five fluorine atoms and one lone pair.
- The molecular geometry is **square pyramidal**.

3. **IF5**:
- Iodine (I) is the central atom with five fluorine atoms and one lone pair.
- The molecular geometry is also **square pyramidal**.

### Step 2: Analyze the second set of molecules
4. **SF4**:
- Sulfur (S) is the central atom with four fluorine atoms and one lone pair.
- The molecular geometry is **seesaw** due to the presence of the lone pair.

5. **XeOF4**:
- Xenon (Xe) is the central atom with one oxygen and four fluorine atoms, plus one lone pair.
- The molecular geometry is **square pyramidal**.

6. **PCl4⁺**:
- Phosphorus (P) is the central atom with four chlorine atoms and no lone pairs.
- The molecular geometry is **tetrahedral**.

### Step 3: Analyze the third set of molecules
7. **SF6**:
- Sulfur (S) is the central atom with six fluorine atoms.
- The molecular geometry is **octahedral**.

8. **PF6⁻**:
- Phosphorus (P) is the central atom with six fluorine atoms.
- The molecular geometry is also **octahedral**.

9. **IOF5**:
- Iodine (I) is the central atom with one oxygen and five fluorine atoms, plus one lone pair.
- The molecular geometry is **square pyramidal**.

### Step 4: Analyze the last set of molecules
10. **COCl2**:
- Carbon (C) is the central atom with two chlorine atoms and a double bond with oxygen.
- The molecular geometry is **trigonal planar**.

11. **SOCl2**:
- Sulfur (S) is the central atom with two chlorine atoms and a double bond with oxygen, plus one lone pair.
- The molecular geometry is **bent** or **pyramidal**.

12. **XeOF2**:
- Xenon (Xe) is the central atom with two fluorine atoms and one oxygen, plus three lone pairs.
- The molecular geometry is **T-shaped**.

### Conclusion
From the analysis, we find that the following molecules have the same geometry:
- **SbF5**
- **XeF5⁻**
- **IF5**
- **XeOF4**
- **IOF5**

Thus, the correct answer is that the molecules **SbF5, XeF5⁻, IF5, XeOF4, and IOF5** have the same geometry, which is **square pyramidal**.
