- DO H C - C H 2 14 - C H 2 - C O O - N a +
Correct answer
B. C H 3 - C H 2 14 - C H 2 N H 2
Step-by-step solution
Every surfactant contains two parts a hydrophobic part and a hydrophilic part. Hydrophobic part belongs to the long non polar carbon chain with some side chains. It is called as hydrophobic because it does not interact witht the water or water repellant. Hydrophilic part belongs to the ionic head of the surfactant. It attracts the water molecules towards itself and combine with the water. It is water loving part. Every surfactant must consists both of these hydrophobic and hydrophilic part for better cleansing abil
