During an oil spill oil coats the surface of the water endangering sea life. Why doesn and rsquot oil dissolve in ocean water?

Oil doesn't dissolve in ocean water primarily because it is hydrophobic, meaning it repels water molecules. The molecular structure of oil is nonpolar, while water is polar, leading to a lack of attraction between the two substances. Additionally, the cohesive forces among water molecules are stronger than the interactions between water and oil, preventing oil from mixing. This results in oil forming a surface layer on the water, which can be harmful to marine life.
