Detailed explanation-1: -Hydrophobic and hydrophilic are opposites. The word stem ‘hydr’ comes from the greek ‘hydor’ meaning water, therefore hydrophobic materials are ‘water-fearing’, and do not mix with water, whereas hydrophilic materials are ‘water-loving’ and have a tendency to be wetted by water.

Detailed explanation-2: -Hydrophilic (biology definition): water-loving; having an affinity for water; capable of interacting with water through hydrogen bonding. Etymology: from Greek hydros, meaning “water” and philia, meaning “friendship”. Compare: hydrophobic. Hydrophilic substances are polar in nature.

Detailed explanation-3: -Hydrophilic means having an affinity for water.

Detailed explanation-4: -Materials with a special affinity for water-those it spreads across, maximizing contact-are known as hydrophilic. Those that naturally repel water, causing droplets to form, are known as hydrophobic.

Detailed explanation-5: -Hydrophobic is a property of molecules that do not mix with water. The definition of hydrophobic can be sorted out from the Greek etymology of the word. “Hydro” means water and “phobic” means fearing. Thus, hydrophobic molecules, also called hydrophobes, are water fearing molecules.
