Soap molecules have a polar end and a nonpolar end. The polar end of the soap molecule attracts and interacts with water molecules, while the nonpolar end interacts with and attracts oil and grease molecules. When soap is added to water, the nonpolar ends of the soap molecules surround and trap the grease molecules, while the polar ends face outwards and interact with the water molecules, allowing the grease to be washed away in the water.
