EVERYDAY SCIENCE

Detailed explanation-1: -Hydrophobic means lacking an affinity for water; insoluble in water; repelling water. Examples of hydrophobic molecules include alkanes, oils, fats, and greasy substances in general.

Detailed explanation-2: -This means that it repels water. The word hydrophobic literally means afraid of water: hydro = water and phobia = fear. For example, ever heard of arachnophobia? It’s the fear of arachnids like spiders!

Detailed explanation-3: -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-4: -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-5: -Hydrophobic molecules and surfaces repel water. Hydrophobic liquids, such as oil, will separate from water. Hydrophobic molecules are usually nonpolar, meaning the atoms that make the molecule do not produce a static electric field.
