The antiseptic action of Dettol is due to

Options

A. Chlorobenzene
B. Chloroxylenol
C. Chloroquine
D. Chloramphenicol

Answer

To determine the antiseptic action of Dettol, we need to identify the active ingredient responsible for its antibacterial properties. Let's break down the options provided:

1. **Chlorobenzene**: This compound is primarily used as a solvent and does not have significant antiseptic properties.

2. **Chloroxynolol**: This is a known antiseptic agent. It has moderate antibacterial effects and is commonly used in various antiseptic formulations, including Dettol.

3. **Chloroquine**: This is an antimalarial drug and does not have antiseptic properties.

4. **Chlorochloramphenicol**: While chloramphenicol is an antibiotic, the term "Chlorochloramphenicol" is not commonly recognized, and chloramphenicol itself is not the active ingredient in Dettol.

Given this analysis, we can conclude that the antiseptic action of Dettol is primarily due to **Chloroxynolol**.

Thus, the answer is **option B: Chloroxynolol**.

### Step-by-Step Solution:
1. **Identify the options**: The question provides four compounds: Chlorobenzene, Chloroxynolol, Chloroquine, and Chlorochloramphenicol.

2. **Evaluate each compound**:
- **Chlorobenzene**: Not an antiseptic.
- **Chloroxynolol**: Known for its antiseptic properties.
- **Chloroquine**: Used for malaria treatment, not antiseptic.
- **Chlorochloramphenicol**: Not a recognized antiseptic.

3. **Select the correct answer**: Based on the evaluation, Chloroxynolol is the only compound with antiseptic action.

4. **Final conclusion**: The antiseptic action of Dettol is due to Chloroxynolol, making the correct answer **option B**.
