The structure and function of soap is best represented by which of the following

Question

The structure and function of soap is best represented by which of the following descriptions?

A. Soap possesses both hydrophilic and hydrophobic portions.

B. The hydrophobic portion interacts with the water and the hydrophilic portion interacts with the oil to clean.

C.Soap removes grease from pans and clothes by using the nonpolar ends of the soap particles to interact with the grease and thus the surface of the grease is covered with the polar/ionic portions of the soap particles and can interact with the water.

D.Soap forms three dimensional units called micelle units in water that have the polar ends of the soap inside interacting with water and the nonpolar ends on the outside interacting with oil/grease/dirt.

E.The descriptions in a and c are both correct.

F.The descriptions in b and c are both correct.

G.None of these descriptions are correct.

Explanation / Answer

Soap has two parts parts namely polar (hydrophilic) and non polar (hydrophobic) in which hydrophobic part intearcts with grease and thus surface of grease is covered with hydrophilic part and therefore forms a micelle with hydrophilic(polar) part pointing outwards.

So, on concluding , option E is the correct statement.
