statement is not valid for which of the following hybridisation.

A. `sp^(3)`
B. `sp^(2)`
C. `sp^(3)d^(2)`
D. sp

Answer

To determine which hybridization does not conform to the statement "the hybrid orbitals are at angle of X degrees to one another," we need to analyze the angles associated with different types of hybridization.

### Step-by-Step Solution:

1. **Identify the Hybridizations**: The common hybridizations we will analyze are sp3, sp2, sp3d2, and sp.

2. **Analyze sp3 Hybridization**:
- In sp3 hybridization, the hybrid orbitals are arranged in a tetrahedral geometry.
- The bond angle is approximately **109.5 degrees** (or 109 degrees 28 minutes).
- Since this angle is not a simple degree measurement, it does not conform to the statement.

3. **Analyze sp2 Hybridization**:
- In sp2 hybridization, the hybrid orbitals are arranged in a trigonal planar geometry.
- The bond angle is **120 degrees**.
- This angle is a simple degree measurement, so it conforms to the statement.

4. **Analyze sp3d2 Hybridization**:
- In sp3d2 hybridization, the hybrid orbitals are arranged in an octahedral geometry.
- The bond angles include **90 degrees** and **180 degrees**.
- These angles are also simple degree measurements, so they conform to the statement.

5. **Analyze sp Hybridization**:
- In sp hybridization, the hybrid orbitals are arranged in a linear geometry.
- The bond angle is **180 degrees**.
- This angle is a simple degree measurement, so it conforms to the statement.

6. **Conclusion**:
- The only hybridization that does not conform to the statement "the hybrid orbitals are at angle of X degrees to one another" is **sp3**, because its angle is expressed in degrees and minutes (109 degrees 28 minutes).

### Final Answer:
**The hybridization that does not conform to the statement is sp3.**
