The adjective hydrophilic describes something that 'likes water' (from Greekhydros = water; philos = friend).
A hydrophilic molecule or portion of a molecule is one that typically is electrically polarized and capable of H-bonding, enabling it to dissolve more readily in water than in oil or other "non-polar" solvents.
Hydrophilic molecules can establish hydrogen bonds with water molecules (H2O). This is favourable by thermodynamics and makes these molecules soluble in water.
A hydrophilicmolecule or portion of a molecule is one that is typically charge-polarized and capable of hydrogen bonding, enabling it to dissolve more readily in water than in oil or other hydrophobic solvents.
Soap has a hydrophilic head and a hydrophobic tail which allows it to dissolve in both waters and oils, therefore allowing the soap to clean a surface.
