Which of the following contain `sp^(2)` hybridised carbon bonded to X?

Options

A.
B.
C.
D.

Answer

To determine which of the given compounds contains an sp² hybridized carbon bonded to a halogen (X), we need to analyze the hybridization of the carbon atoms in each compound. The hybridization of a carbon atom can be determined by counting the number of sigma bonds and lone pairs around it.

### Step-by-Step Solution:

1. **Identify the Structure of Each Compound**:
- Look at the molecular structure of each compound provided in the question. Identify the carbon atoms and their bonding environment.

2. **Count Sigma Bonds**:
- For each carbon atom, count the number of sigma bonds it forms. A sigma bond is formed by the head-on overlap of orbitals.
- The formula for determining hybridization based on the number of sigma bonds and lone pairs is:
- **sp**: 2 sigma bonds
- **sp²**: 3 sigma bonds
- **sp³**: 4 sigma bonds

3. **Determine Hybridization**:
- If a carbon atom has three sigma bonds (and no lone pairs), it is **sp² hybridized**.
- If a carbon atom has four sigma bonds, it is **sp³ hybridized**.

4. **Check for Bonding with X**:
- Ensure that the sp² hybridized carbon is bonded to a halogen (X). This means that one of the sigma bonds must be with a halogen atom.

5. **Conclusion**:
- After analyzing all the compounds, identify which one has an sp² hybridized carbon bonded to X.

### Example:
- If we have a compound like **vinyl chloride (C2H3Cl)**:
- The carbon bonded to Cl has 3 sigma bonds (2 with H and 1 with Cl), indicating it is sp² hybridized.

### Final Answer:
- The compound that contains sp² hybridized carbon bonded to X is **vinyl chloride (C2H3Cl)**.
