Detailed explanation-1: -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-2: -Water naturally forms hydrogen bonds with itself and other polar and charged molecules. Hydrophobic molecules are not able to form these hydrogen bonds and thus disrupt the hydrogen bond network. This forces the water molecules to reform a hydrogen bond cage around the hydrophobic molecule.

Detailed explanation-3: -Something defined as hydrophilic is actually attracted to water, while something that is hydrophobic resists water. This means when hydrophobic items come in contact with liquids, water is encouraged to bead up and roll off the surface-almost pushing it away like a magnet pushes away metal objects.

Detailed explanation-4: -Hydrophobic literally means “the fear of water”. Hydrophobic molecules and surfaces repel water. Hydrophobic liquids, such as oil, will separate from water.
