Why is oil hydrophobic?
Understand the Problem
The question is asking for the reasons behind oil's hydrophobic nature, likely focusing on its molecular structure and interactions with water.
Answer
Oil is hydrophobic because it is nonpolar.
Oil is hydrophobic because it is nonpolar and repelled by polar water molecules.
Answer for screen readers
Oil is hydrophobic because it is nonpolar and repelled by polar water molecules.
More Information
Oil molecules are made up of carbon and hydrogen atoms, which form nonpolar covalent bonds. This lack of polarity means that oil molecules do not form hydrogen bonds with water, leading to their separation.
Tips
A common mistake is confusing hydrophobic (water-fearing) with hydrophilic (water-loving). Hydrophobic substances do not dissolve in water because they lack polarity.
