Quizplus · Accepted Answer

In a soap micelle, the hydrophilic (water-loving) region is on the surface and the hydrophobic (water-fearing) region is in the interior. This is because the hydrophilic head of the soap molecule is attracted to water, while the hydrophobic tail is repelled by water. The hydrophobic tails cluster together in the center of the micelle, shielding themselves from the surrounding water, while the hydrophilic heads face outward, interacting with the water molecules.
