How is a polar compound related to hydrophilic and hydrophobic interactions?
Similar to Like dissolves Like
A substance's ability to interact with water should be preferred whether it is hydrophobic (hates water) or hydrophilic (loves water).
For instance, ethanol is hydrophilic because, in addition to being a polar molecule, it can carry H-bond, dipole-dipole, and London dispersion force (LDF) with water.
Hexane is another example of an apolar molecule that can only carry weak interactions, or LDF interactions, making it hydrophobic.

Polar compounds have polar bonds, which form regions of partial positive and negative charges, allowing them to form hydrogen bonds with water molecules. This interaction makes polar compounds soluble in water, whereas hydrophobic compounds, lacking polar bonds, do not readily dissolve in water. Polar compounds interact with water molecules through hydrophilic interactions, meaning they have an affinity for water, while nonpolar compounds tend to repel water and engage in hydrophobic interactions.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
