Name the process which occurs when a drop of dettol is added to water

The process is diffusion .

Diffusion only.... above students are right...

Diffusion occurs as the dettol molecules accommodate between the water molecules. Also when you pour even a small amount of that water dissolved dettol to another bucket of water, you will still find that you can smell dettol. This is because particles of matter show diffusion/

when a drop of dettol is added to water ,the process of diffusion takes place as the particles of dettol get mixed with the particles of water due to constantly movement of particles.
