Which Bond Or Interaction Would Be Difficult To Disrupt When Compounds Are Put Into Water?

A large portion of modern chemical research is focused on discovering new compounds and how they interact with one another. Many of these compounds are designed to either change a bond between atoms or to disrupt an interaction between atoms or molecules.

Some of the most widely used chemicals are pesticides. These chemicals are designed to specifically target organisms, usually insects. By changing the structure of the insect, it is no longer able to survive.

The ability to design compounds that can selectively disrupt specific bonds or interactions is what makes them so powerful. An example of a compound that selectively disrupts a bond is hydrochloric acid which dissolves calcium carbonate (limestone).

Van der Waals interactions

Aside from the strongly-binding interactions described above, compounds in water can interact via weaker (but still significant) van der Waals interactions.

These interactions are between the molecules of the compound and the surrounding water molecules. They are named after Dutch physicist D. J. van der Waals, who first proposed such interactions in 1873.

Van der Waals forces are primarily a result of the polarization of atoms and molecules due to electric and magnetic fields. These fields are caused by neighboring molecules or atoms, which in turn influence the adjacent molecule or atom’s behavior.

The influence can be either positive or negative, depending on the type of atom or molecule and how many of them there are nearby.

In general, van der Waals forces are weaker than other types of chemical bonding (such as covalent or ionic bonds). However, they play an important role in determining a substance’s properties, such as its shape and volume.

Ion interactions

The second most important group of compounds in water is ionic compounds. These are molecules that have a positive or negative charge. The difference between these types of molecules is the amount of charge they have.

Ionic compounds can be atoms or molecules that are dissolved in water. Atoms of one substance can be dissolved in another substance, which is what happens when we dissolve salt in water.

Water has a strong attraction to ions. This attraction is known as a hydration shell. Ions can be embedded in this shell, and other ions can interact with it.

These interactions are what make it difficult to disrupt chemical reactions when compounds are put into water. Ion interactions prevent the compound from fully coming into contact with other substances, such as water. This prevents some dissolutions and reactions from happening.

Dipole-dipole interactions

Another important force that holds molecules together is the dipole-dipole interaction. This force occurs between two polar molecules or between a polar molecule and the water molecules it is interacting with.

Like charges are repelled and unlike charges are attracted, which results in the interaction of the molecule with water being slightly separated from the water. This causes a slight distortion of the surrounding water molecules, creating a dip in the surface of the water.

This interaction is similar to how grease and water do not mix. The grease is polar, so it does not blend with the non-polar water. This separation creates a dip in the surface of the water, showing that there is a difference in polarity.

Dipole-dipole interactions play a large role in biogeochemical processes like ocean acidification. Changes in pH can alter which chemicals interact via dipole-dipole interactions, potentially disrupting essential processes like coral reef formation.

Hydrophobic interactions

Another type of bond is called a hydrophobic (or water-fearing) interaction. These bonds occur when a molecule or compound has an attractive force with another compound through a water molecule.

For example, in the case of iodine in the bloodstream, it attaches to hemoglobin, the protein in red blood cells that carries oxygen.

Iodine does not attach to hemoglobin in blood plasma, however; it only attaches in blood vessels where there is less oxygen.

This is why you often hear about people using iodine drops to disinfect water: it targets the bonds between iodine and other compounds only when there is less oxygen present.

The problem with completely removing all bonds between compounds and water is that this would also take away necessary nutrients and needed substances for cleaning water.

Ionic bonds

Ionic bonding is one of the strongest types of bonds. These bonds are formed when a negative and positive charge come together. They are called ions because they are atoms that have either a positive or negative charge.

Ionic compounds, like salts, dissolve easily in water because these atoms can be split into two individual parts: a cation and an anion. The cation is the positive ion, and the anion is the negative ion. When these two come together in a compound, they form an ionic bond.

Ionic compounds can be hard to disrupt because you would need to break both the cation-anion and atom-atom bonds. This would take a lot of energy! Disrupting only the cation-anion bonds would not work, as there are no atom-atom bonds within salts.

Covalent bonds

When compounds are put into water, covalent bonds are the most resistant to disruption. This is because the hydrogen bonds required to separate the compound into ions or atoms is extremely difficult.

Ionic compounds can be disassociated in water by breaking down the Coulombic force that holds the ions together. This can be done through changing the temperature of the solution or adding in a different ion that will compete for association.

Lewis bases can be disrupted by breaking apart the association of the molecules with water. If a compound is a non-polar one, then dispersing it in oil will disassociate it. If it is polar, then pouring it down the drain will disperse it.

Ionic compounds can be further disrupted by adding in more ions of opposite charge to them. They will then either dissolve or separate depending on their specific nature.
