Which of the following terms best describes the exterior surface of a soap micelle in water?
A) hydrophobic
B) hydrophilic
C) hard
D) saponified
E) hydrogenated
Soap Micelle
Spherical aggregates formed by soap molecules in aqueous solution, where the hydrophobic tails are sequestered inwards and the hydrophilic heads face outward.
Exterior Surface
The outermost boundary or layer of an object, material, or geometrical space that is exposed to the environment or another medium.
Hydrophilic
Describes molecules or substances that have a strong affinity for water, often because of the presence of polar groups.
- Detect and expound on the arrangement and properties of soap and detergent molecules.
- Explain the concept of micelles, their formation, and their role in the action of soaps and detergents.

Final Answer :
B
Explanation :
The exterior surface of a soap micelle in water is hydrophilic, meaning it is attracted to water. This is due to the presence of the ionic, hydrophilic (-COO-) end of the soap molecule on the outer surface of the micelle. The hydrophobic (-CH2-) end is facing the interior of the micelle, away from the water.
