In a micelle, how are the polar and non-polar regions arranged?

1. The polar part lies on the outside, while the non-polar part is on the inside
2. The polar part lies on the inside, while the non-polar part is on the outside
3. Both polar and non-polar parts are spread uniformly over the surface
4. They are found only at the surface

Correct answer: The polar part lies on the outside, while the non-polar part is on the inside

Solution

In a micelle, the polar regions face outward toward the surrounding water, allowing for interaction with the aqueous environment, while the non-polar regions are tucked away inside, minimizing their exposure to water and stabilizing the structure.
