Question

Position of non polar & polar part in micelle:

• A. polar at outer surface but non polar at inner surface
• B. polar at inner surface non polar at outer surface
• C. distributed over all the surface
• D. are present in the surface only

Answer 1

The correct option is A polar at outer surface but non polar at inner surface

A micelle is an aggregate of surfactant molecules dispersed in a liquid colloid.

Micelles contain polar head groups that usually form the outside as the surface of micelles. They face to the water because they are polar. The hydrophobic tails are inside and away from the water since they are non-polar.
