What is the hybridization of the carbon atom in the allylic halides ?

Options

A. `sp^3` hybridisation
B. sp hybridisation
C. `sp^3d^3` hybridised
D. None of these

Answer

To determine the hybridization of the carbon atom in allylic halides, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure of Allylic Halides**:
- Allylic halides are compounds where a halogen atom is attached to a carbon atom that is adjacent to a carbon-carbon double bond (alkene). The carbon atom next to the double bond is referred to as the allylic carbon.

2. **Analyze the Carbon Atom**:
- In allylic halides, the carbon atom that is directly bonded to the halogen is the one we need to analyze for hybridization.

3. **Count the Bonds**:
- The carbon atom in question typically forms four sigma (σ) bonds. This includes:
- One bond with the halogen.
- Two bonds with adjacent carbon atoms (one of which is part of the double bond).
- One bond with another carbon atom that may be part of the chain.

4. **Determine Hybridization**:
- Since the carbon atom forms four sigma bonds, it undergoes sp³ hybridization. The presence of the double bond in the adjacent carbon atoms (which are sp² hybridized) does not affect the hybridization of the allylic carbon itself.

5. **Conclusion**:
- Therefore, the hybridization of the carbon atom in allylic halides is **sp³**.
