Incorrect statement is

Options

A. Hybridisation is intermixing of orbitals of nearly equal energies
B. Hybrid orbitals are identical in all respect
C. Hybrid orbitals can form `sigma` bond and `pi` bond
D. `Shape of molecule depends upon type of hybridisation only

Answer

To determine the incorrect statement regarding hybridization, let's analyze the given statements step by step.

### Step 1: Understand Hybridization
Hybridization is the process of mixing atomic orbitals to form new hybrid orbitals that are suitable for the pairing of electrons to form chemical bonds. The key points to remember are:
- Hybridization involves orbitals of nearly equal energy.
- Hybrid orbitals are used to form sigma bonds, while pi bonds are formed from unhybridized p orbitals.

### Step 2: Analyze Each Statement
1. **Statement 1**: "Hybridization is intermixing of orbitals of nearly equal energy."
- This statement is **correct**. Hybridization involves orbitals that are of similar energy levels.

2. **Statement 2**: "Hybridization is intermixing of orbitals of same and nearly equal energy."
- This statement is also **correct**. It emphasizes that the orbitals can be the same or nearly equal in energy.

3. **Statement 3**: "Only sigma bonds are formed from hybrid orbitals, not pi bonds."
- This statement is **correct**. Hybrid orbitals are used to form sigma bonds, while pi bonds are formed from unhybridized p orbitals.

4. **Statement 4**: "The shape of the molecule depends upon the type of hybridization."
- This statement is **correct**. The geometry and shape of a molecule can be predicted based on the type of hybridization that occurs.

### Step 3: Identify the Incorrect Statement
After analyzing all four statements, we find that all the statements provided are correct. However, if we need to identify a statement that could be misleading or incorrect based on typical misunderstandings about hybridization, we could argue that the phrasing in one of the statements might imply a misunderstanding.

In this case, if there was an option that stated something like "Hybridization can occur between orbitals of significantly different energy levels," that would be incorrect. However, since all statements provided are correct, the question may be misleading.

### Conclusion
Based on the analysis, if we were to choose an incorrect statement based on common misconceptions, it would be one that suggests hybridization can occur between orbitals of significantly different energy levels. However, since all provided statements are correct, we conclude that there is no incorrect statement among the given options.
