Question 7 • Chemistry

When applied to a dish, soap makes grease soluble in water. Which explanation correctly supports the role of intermolecular forces in this common observation?

Answer
A
The polar soap molecule attaches itself to a nonpolar soap molecule.
B
The polar soap molecule attaches itself to the dish.
C
The nonpolar end of a soap molecule attaches itself to water.
D
The nonpolar end of a soap molecule attaches itself to grease.

Explanation

Soap molecules have a nonpolar end and a polar end. The nonpolar end is attracted to nonpolar grease, while the polar end interacts with water, allowing the grease to be carried away when rinsed. Thus, the nonpolar end attaching to grease supports how soap helps grease mix with water.
