Assertion (A): Micelle formation occurs when soap is dissolved in water. Reason (R): The hydrophobic tails of soap molecules cluster together to avoid water, while the hydrophilic heads face outward.
A. A is false but R is true.
B. Both A and R are true and R is the correct explanation of A.
C. A is true but R is false.
D. Both A and R are true but R is NOT the correct explanation of A.
Answer: Option B
Solution (By JKExamLibrary)
In water, soap molecules arrange themselves into spherical aggregates called micelles. The hydrophobic hydrocarbon tails point inward, away from water, while the hydrophilic ionic heads point outward, interacting with water. This structure traps oily dirt in the center, allowing it to be washed away.
