Examples of hydrophobic substances include fats, oils, waxes, alkanes and other greasy substances. The term hydrophobic comes from the Greek and is translated as “having a horror of water” or “water fearing.” In other words, hydrophobicity is a property of a substance that repels water.


To be hydrophobic means to fear water. In chemistry, it refers to the property of a substance to repel water. It isn't that the substance is repelled by water so much as it has a lack of attraction to it. A hydrophobic substance exhibits hydrophobicity and may be termed hydrophobic.


Substances are hydrophobic because they are nonpolar. Nonpolar molecules are made up of elements with little difference in their electronegativities so they do not have charges or partial charges.


Water on hydrophobic surfaces will exhibit a high contact angle. 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.


Hydrophobic interactions describe the relations between water and hydrophobes (low water-soluble molecules). Hydrophobes are nonpolar molecules and usually have a long chain of carbons that do not interact with water molecules. The mixing of fat and water is a good example of this particular interaction.


hydrophilic means water-loving, but is usually used in the context of substances that are easily wetted, but do not dissolve. So although table salt is technically hydrophilic, the term is not used to describe salt. Concrete, on the other hand is ...


Example, sodium and chlorine, NaCl (table salt) Substances that have an affinity for water are hydrophilic, those that seem to repel water are hydrophobic Google hydrophilic substances and you ...


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. In polar molecules these opposite regions of electrical energy attract to water molecules.


Diffusion allows them to distribute substances with little to no energy on their part. Examples of Hydrophilic Sugar. Sugar, or more specifically glucose, is a molecule that many types of cells use as an energy source. A molecule of glucose has both hydrophobic and hydrophilic portions. The picture below shows a molecule of glucose.


All of the other answers use lots of words but no pictures. I thought I’d do the opposite, using as many pictures as possible to explain hydrophilic, hydrophobic, ultrahydrophobic, ultrahydrophilic, and amphipathic. Source: What is meant by hydrop...
