Position of non-polar and polar part in micelle is

1. polar at outer surface and non-polar at inner surface
2. polar at inner surface and non-polar at outer surface
3. distributed all over the surface
4. present in the surface only

Correct answer: polar at outer surface and non-polar at inner surface

Solution

In a micelle, the polar (hydrophilic) part is oriented towards the outer surface interacting with water, while the non-polar (hydrophobic) part is sequestered in the inner core to avoid water.
