Why are micelles not formed when soap is added to ethanol
Answers
Answer:
No, micelle formation does not take place in ethanol because the alkyl chain of soap becomes soluble in alcohol. Micelles can be formed only around suspended molecules of oil in a mixture. ... For soaps to form micelles it is necessary that the hydrophobic end sticks to the dirt (dirt is generally organic in nature).
Micelles not formed when soap is added to ethanol bcoz the long hydrocarbon chain is soluble in ethanol and in other organic solvents so hydrocarbon gets attached to ethanol particles. The remaining ionic part which is water-attracting does not sticks to anything in ethanol. So neither hydrocarbon chain sticked to dirt particle present in ethanol nor short ionic part sticked to dirt particle. And for the formation of a micelle it is necessary that hydrocarbon chain stick to dirt particle which didn't happen in case of ethanol. So a micelle is not formed.
