The antiseptic action of dettol is due to :

Question

Accepted Answer

Dettol is a widely used antiseptic product, and its antiseptic action is primarily due to the presence of chloroxylenol, which is Option 2. Chloroxylenol is a chemical compound known for its antimicrobial properties, making it effective in killing bacteria and fungi. It works by disrupting the cell walls of microorganisms, leading to their death and thus preventing infections. This makes chloroxylenol an ideal ingredient in antiseptic formulations like Dettol, which are used to clean wounds and disinfect surfaces.

Now, let's examine why the other options are incorrect:

1. **Chlorobenzene**: This compound is an aromatic organic compound used primarily as a solvent in the production of other chemicals. It does not possess significant antiseptic properties and is not used for antimicrobial purposes. Therefore, it is not responsible for the antiseptic action of Dettol.

3. **Chloroquine**: Chloroquine is a medication used to prevent and treat malaria. It has no antiseptic properties and is not used in formulations like Dettol. Its primary function is as an antimalarial drug, not as an antimicrobial agent for topical use.

4. **Chloroacetylene**: This is a highly reactive and unstable compound used in chemical synthesis. It is not used in antiseptic products and does not have antimicrobial properties. Its instability and reactivity make it unsuitable for use in consumer products like Dettol.

In conclusion, chloroxylenol (Option 2) is the correct answer because it is the active ingredient in Dettol responsible for its antiseptic action, effectively killing bacteria and fungi to prevent infections. The other options do not have the necessary properties to serve as antiseptics in this context.
