Anions, which are negatively-charged ions, can be either soluble or insoluble in water. What Are Some Examples of Covalent Compounds? Polar covalent bonds involve the sharing of electrons between two atoms, with one atom having a stronger attraction for the electrons than the other, resulting in an uneven distribution of charge wihin the bond. Tearing down a portion of the clathrate cage will cause the entropy to increase ( \( \Delta S \) is positive), since forming it decreases the entropy. They have hydrophobic carbon tails and hydrophilic head groups. This creates a dipole moment, which makes the molecule attracted to water molecules. The head, which is located on the outer side of the membrane, is hydrophilic (water-loving), whie the tail, which is located on the inner side of the membrane, is hydrophobic (water-fearing). Well, the answer is both! Because ions are attracted to the water molecules in this way, they are said to be hydrophilic. Hydrocarbons are another type of hydrophobic molecule that contain only hydrogen and carbon atoms in their structure; they include alkanes, alkenes, and aromatics. These hydrogels are known for their ability to absorb water and swell. Ions can be generally divided into two categories: cations (positively charged ions) and anions (negatively charged ions).
