Select in which both have sea-saw shape-

Options

A. `XeO_(2)F_(2),SiF_(4)`
B. `XeO_(2)F_(2),IOF_(2)^(-)`
C. `TeCl_(4),ICl_(4)^(-)`
D. `BrO_(3)F,XeOF_(2)`

Answer

To determine which option contains compounds that both have a "see-saw" shape, we will analyze each option based on the hybridization and molecular geometry of the compounds listed.

### Step-by-Step Solution:

1. **Identify the Compounds in Each Option:**
- **Option A:** XeO2F2 and SiF4
- **Option B:** XeO2F2 and IOF2^-
- **Option C:** Cl4 and ICl4^-
- **Option D:** BrO3F and XeOF2

2. **Analyze Option A:**
- **XeO2F2:**
- Hybridization: SP3D
- Geometry: 4 bond pairs and 1 lone pair → See-saw shape.
- **SiF4:**
- Hybridization: SP3
- Geometry: 4 bond pairs and 0 lone pairs → Tetrahedral shape.
- **Conclusion:** Only XeO2F2 has a see-saw shape. **Eliminate Option A.**

3. **Analyze Option B:**
- **XeO2F2:**
- Already established: See-saw shape.
- **IOF2^-:**
- Hybridization: SP3D
- Geometry: 4 bond pairs and 1 lone pair → See-saw shape.
- **Conclusion:** Both compounds have a see-saw shape. **Keep Option B.**

4. **Analyze Option C:**
- **Cl4:**
- Hybridization: SP3
- Geometry: 4 bond pairs and 0 lone pairs → Tetrahedral shape.
- **ICl4^-:**
- Hybridization: SP3D2
- Geometry: 4 bond pairs and 2 lone pairs → Square planar shape.
- **Conclusion:** Neither compound has a see-saw shape. **Eliminate Option C.**

5. **Analyze Option D:**
- **BrO3F:**
- Hybridization: SP3
- Geometry: 4 bond pairs and 0 lone pairs → Tetrahedral shape.
- **XeOF2:**
- Hybridization: SP3D
- Geometry: 4 bond pairs and 1 lone pair → See-saw shape.
- **Conclusion:** Only XeOF2 has a see-saw shape. **Eliminate Option D.**

6. **Final Conclusion:**
- The only option where both compounds have a see-saw shape is **Option B (XeO2F2 and IOF2^-).**

### Final Answer:
**Option B** is the correct answer, as both compounds have a see-saw shape.
