Soap molecules in water form micelles because:
ATheir entire body is hydrophobic under typical conditions
BThey have a hydrophilic head and a hydrophobic tail
CWater expels them in general usage
DThey have ionic chains throughout
Answer & Solution
Correct answer: B. They have a hydrophilic head and a hydrophobic tail
1. Soap molecules have two distinct ends.
2. The hydrocarbon tail is non-polar (hydrophobic).
3. The carboxylate head is polar and ionic (hydrophilic).
4. In water, tails huddle together and heads face outward.
5. The resulting spherical clusters are called micelles.
6. Micelles trap oil droplets inside the tail cluster, enabling cleaning.
