Incorrect statement regarding hybridization is

Options

A. it is not possible for isolated atoms
B. number of hybrid orbital formed is same as the number of orbitals combining
C. only the half filled orbitals and fully filled orbitals can participate not the empty orbital
D. it is not a real physical process

Answer

To determine the incorrect statement regarding hybridization, let's analyze each option step by step.

### Step 1: Understand Hybridization
Hybridization is the process where atomic orbitals mix to form new hybrid orbitals that are degenerate (having the same energy). This occurs in covalently bonded atoms, not in isolated atoms.

### Step 2: Analyze Each Statement
1. **Option A**: "It is not possible for isolated atoms."
- This statement is **correct** because hybridization does not occur in isolated atoms; it requires the presence of covalent bonding.

2. **Option B**: "Number of hybrid orbitals formed is the same as the number of orbitals combining."
- This statement is **correct**. For example, if one s orbital combines with three p orbitals, it forms four sp³ hybrid orbitals. The number of hybrid orbitals equals the number of combining orbitals.

3. **Option C**: "Only the half-filled orbitals and fully filled orbitals can participate, not the empty orbital."
- This statement is **incorrect**. Empty orbitals can also participate in hybridization. Therefore, this is the incorrect statement we are looking for.

4. **Option D**: "It is not a real physical process."
- This statement is **correct**. Hybridization is a theoretical concept used to explain molecular geometry and bonding, not a physical process that can be observed directly.

### Conclusion
After analyzing all the options, the incorrect statement regarding hybridization is **Option C**: "Only the half-filled orbitals and fully filled orbitals can participate, not the empty orbital."

### Final Answer
The answer is **Option C**.
