Interpretation: To explain the formation of micelles.
Concept Introduction: Detergent consists of two parts that are head and tail parts.
Answer to Problem 94A
When detergent molecules aggregate in water, they form organized structures which are known as a micelle.
Explanation of Solution
When detergent molecules aggregate in water, they form organized structures which are known as a micelle. The micelle is formed when detergent is added to water. The two parts of the detergent molecule dissolve in different mediums.
The head part of a micelle is polar in nature while the tail part is non-polar in nature.
The head group in a micelle is hydrophilic (the polar part of a molecule that is water-loving) the tail in a micelle is hydrophobic (the nonpolar part of a molecule that is not water-loving).
Thus, the two parts of the detergent are a head and a tail part that are polar and non-polar in nature respectively.
