Secondary halide among the following is

Options

A. isopropyl chloride
B. isobutyl chloride
C. n - propyl chloride
D. n - butyl chloride

Explanation

To determine which of the given compounds is a secondary halide, we need to understand the classification of haloalkanes based on the carbon atom to which the halogen is attached.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Primary Halide**: A halide where the halogen is attached to a carbon atom that is connected to only one other carbon atom.
- **Secondary Halide**: A halide where the halogen is attached to a carbon atom that is connected to two other carbon atoms.
- **Tertiary Halide**: A halide where the halogen is attached to a carbon atom that is connected to three other carbon atoms.

2. **Identify the Structure of Isopropyl Chloride**:
- Isopropyl chloride has the structure where the chlorine atom is attached to the second carbon of a three-carbon chain (propane).
- The structure can be represented as:
```
CH3
|
CH - Cl
|
CH3
```
- In this structure, the carbon atom attached to the chlorine (C-Cl) is connected to two other carbon atoms (the two CH3 groups).

3. **Classify the Halide**:
- Since the carbon atom to which the chlorine is attached is connected to two other carbon atoms, isopropyl chloride is classified as a **secondary halide**.

4. **Conclusion**:
- Therefore, the secondary halide among the options provided is **isopropyl chloride**.
