Which one of the following does not match with respect to the shape of the molecule ?

Options

A. `NH_(3)`- Trigonal pyramidal
B. `SF_(4)` - Tetrahedral
C. `H_(2)S` - Bent
D. `ClF_(3)` - T-shape

Explanation

To determine which molecule does not match with respect to its shape, we will analyze the shapes of the given molecules one by one.

### Step 1: Analyze Ammonia (NH3)
- **Molecular Geometry**: Ammonia has one lone pair and three bond pairs.
- **Shape**: The presence of the lone pair causes the molecule to adopt a trigonal pyramidal shape.
- **Conclusion**: The shape of NH3 is correctly identified as trigonal pyramidal.

### Step 2: Analyze Sulfur Tetrafluoride (SF4)
- **Molecular Geometry**: SF4 has one lone pair and four bond pairs.
- **Shape**: The molecule adopts a C-shaped (or K-shaped) geometry due to the lone pair.
- **Conclusion**: The shape of SF4 is correctly identified as C-shaped.

### Step 3: Analyze Hydrogen Sulfide (H2S)
- **Molecular Geometry**: H2S has two lone pairs and two bond pairs.
- **Shape**: Similar to water (H2O), H2S has a bent shape.
- **Conclusion**: The shape of H2S is correctly identified as bent.

### Step 4: Analyze Chlorine Trifluoride (ClF3)
- **Molecular Geometry**: ClF3 has two lone pairs and three bond pairs.
- **Shape**: This results in a T-shaped geometry.
- **Conclusion**: The shape of ClF3 is correctly identified as T-shaped.

### Final Conclusion
After analyzing all the given molecules, we find that all shapes have been identified correctly. However, the question asks for the one that does not match with respect to its shape.

The answer is **SF4**, as it is not tetrahedral but rather C-shaped.

### Answer: SF4 does not match with respect to the shape of the molecule.
