* Water is a polar molecule: This means it has a positive end and a negative end due to uneven sharing of electrons. This polarity allows water molecules to form strong hydrogen bonds with each other.
* Hydrophobic molecules are nonpolar: They have an even distribution of electrons and lack the charged regions that would allow them to interact favorably with water molecules.
* "Like dissolves like": Polar molecules tend to dissolve other polar molecules, while nonpolar molecules tend to dissolve other nonpolar molecules.
Think of it this way:
Imagine trying to mix oil and water. Oil is nonpolar, while water is polar. They don't mix because their molecular structures are incompatible.
Instead of dissolving, hydrophobic molecules tend to:
* Cluster together: They avoid contact with water and form separate groups or droplets.
* Form membranes: They often make up the core of biological membranes, creating a barrier between the watery environment inside and outside a cell.
