Detailed explanation-1: -Examples of hydrophobic molecules include the alkanes, oils, fats, and greasy substances in general. Hydrophobic materials are used for oil removal from water, the management of oil spills, and chemical separation processes to remove non-polar substances from polar compounds.

Detailed explanation-2: -In fact, oils are hydrophobic, or “water fearing.” Instead of being attracted to water molecules, oil molecules are repelled by them. As a result, when you add oil to a cup of water the two don’t mix with each other.

Detailed explanation-3: -Examples of Hydrophobic Substances Oils, fats, alkanes, and most other organic compounds are hydrophobic. If you mix oil or fat with water, the mixture will separate. If you shake a mixture of oil and water, the oil globules will eventually stick together to present a minimum surface area to the water.

Detailed explanation-4: -The hydrophobic portion of the emulsifier dissolves in the oil phase, and the hydrophilic portion dissolves in the aqueous phase, forming a dispersion of small oil droplets.

Detailed explanation-5: -Barite, hematite, minerals in drilling fluids, some membranes, glucose/sugar and many other substances are known as hydrophilic. In comparison, oils, proteins, colloids, greases and clays are hydrophobic.
