Select the appropriate statement(s) for classification of haloarene and haloalkane.

Options

A. On the basis of number of halogen atoms.
B. On the basis of compound containing `sp^3 C-X` bond,
C. On the basis of compound containing `sp^2C-X` bond.
D. All of the above

Answer

To classify haloarenes and haloalkanes, we can analyze the statements based on their characteristics. Here's a step-by-step breakdown of the classification:

### Step 1: Classification Based on the Number of Halogen Atoms
- **Haloalkanes and Haloarenes can be classified based on the number of halogen atoms present.**
- **Mono-halogens:** Compounds with one halogen atom.
- **Di-halogens:** Compounds with two halogen atoms.
- **Tri-halogens:** Compounds with three halogen atoms.
- **Poly-halogens:** Compounds with more than three halogen atoms.

### Step 2: Classification Based on Hybridization of Carbon Atoms
- **Haloalkanes can be classified according to the hybridization of the carbon atom bonded to the halogen.**
- **SP3 Hybridization:** In haloalkanes, the carbon atom can be sp3 hybridized, leading to primary (1°), secondary (2°), and tertiary (3°) classifications based on the number of carbon atoms attached to the carbon with the halogen.

### Step 3: Classification of Haloarenes
- **Haloarenes are characterized by the hybridization of the carbon atom to which the halogen is attached.**
- **SP2 Hybridization:** The halogen is bonded to a carbon atom that is sp2 hybridized, typical in aromatic compounds.

### Step 4: Additional Classifications
- **Allylic Compounds:** These can also be classified under sp3 hybridization, where the halogen is attached to a carbon adjacent to a double bond.

### Conclusion
Based on the above classifications, we can conclude that all the statements regarding the classification of haloarenes and haloalkanes are valid. Therefore, the correct answer is that all of the above classifications apply.
