What is the chemical structure of soap and detergent molecules?
Hydrophilic head and hydrophobic tail
Hydrophilic head and hydrophilic tail
Hydrophobic head and hydrophobic tail
Hydrophilic tail and hydrophobic head
Correct answer is A
Both soap and detergent molecules have a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail. The hydrophilic head allows the molecules to interact with water, while the hydrophobic tail interacts with oils and grease.
