Answer

To determine which of the following hybridization geometries is incorrectly matched, we will analyze each option step by step.

### Step 1: Analyze Option 1
- **Hybridization**: sp³d
- **Geometry**: Triangular bipyramidal
- **Orbitals Used**: s + px + py + pz + dz²

**Evaluation**:
- The geometry for sp³d hybridization is indeed triangular bipyramidal, and the orbitals used are correctly identified.
- **Conclusion**: This option is correct.

### Step 2: Analyze Option 2
- **Hybridization**: sp³d³
- **Geometry**: Pentagonal bipyramidal
- **Example**: IF₇
- **Orbitals Used**: s + px + py + pz + dx²-y² + dz² + dxy

**Evaluation**:
- The geometry for sp³d³ hybridization is pentagonal bipyramidal, and IF₇ is a valid example. The orbitals used are also correct.
- **Conclusion**: This option is correct.

### Step 3: Analyze Option 3
- **Hybridization**: sp³d²
- **Geometry**: Capped octahedral
- **Orbitals Used**: s + px + py + pz + dx²-y² + dz²

**Evaluation**:
- The geometry for sp³d² hybridization is octahedral, not capped octahedral. Capped octahedral refers to sp³d³ hybridization, which is distorted octahedral. An example of sp³d² is SF₆, while XeF₆ is an example of sp³d³.
- **Conclusion**: This option is incorrect.

### Step 4: Analyze Option 4
- **Hybridization**: sp³
- **Geometry**: Tetrahedral
- **Orbitals Used**: s + px + py + pz

**Evaluation**:
- The geometry for sp³ hybridization is tetrahedral, and the orbitals used are correctly identified.
- **Conclusion**: This option is correct.

### Final Conclusion
The incorrectly matched option is **Option 3** (sp³d² with capped octahedral geometry).
