What are hydrophobic molecules (or hydrophobic molecular areas)? Describe hydrophilic molecules? How can they be characterized in association to their polarity?

E

Expert

Verified

Hydrophobic molecules are such that contain little or no propensity to dissolve in water (hydro = water, phobia = fear).

Hydrophilic molecules are such that encompass great propensity to dissolve in the water (philia = friendship).

The water is a polar substance. Keeping in mind that the rule which “equal dissolves equal” one can wrap up that hydrophobic substances are non-polar molecules whereas hydrophilic molecules are polar molecules.
