Question

what is micelles and how is micelles formed pls answer​

Answer 1

Hey mate ☺

Micelle or micella is an aggregate of surfactant molecules dispersed in a liquid colloid. A typical micelle in aqueous solution forms an aggregate with the hydrophilic "head" regions in contact with surrounding solvent, sequestering the hydrophobic single-tail regions in the micelle centre.

The formation of a micelle is a response to the amphipathic nature of fatty acids, meaning that they contain both hydrophilic regions (polar head groups) as well as hydrophobic regions (the long hydrophobic chain).

Hope it helps you ☺✌✌

Answer 2

Hey buddy here is your answer.

A spherical aggregate of soap molecules in the soap solution in water is called a micelle.

Micelle Formation

The solvent polarity which determines the interactions of its molecules with polar and non-polar regions of surfactant molecules, plays an important role in the formation of micelles in non-aqueous medium.

For micelle formation to take place the medium has to be a "good solvent" for hydrocarbon chains only. Micelles do not form in the medium of nature similar to both parts of di-philic surfactant molecules; the surfactant reveal only true solubility in such medium. Low alcohols which are good solvents for both polar and non polar regions of surfactant molecules are the typical examples for such media.

Thank you.
