Are hydrogen bonds an example of adhesion or cohesion?

Answers

Answer 1

Answer: They are an example of Cohesion, but barely so. Hope that my answer was useful.

Answer 2

Answer:

Final answer:

Hydrogen bonds can facilitate both adhesion and cohesion. Cohesion is the attraction between similar substances, while adhesion is the attraction between different substances. Both types of interactions can involve hydrogen bonding.

Explanation:

Hydrogen bonds are an example of both adhesion and cohesion. These are types of intermolecular forces. Cohesion refers to the attraction between particles of the same substance, such as water molecules to each other, which is largely due to hydrogen bonding. Adhesion, on the other hand, refers to the attraction between two different types of substances, such as water to glass, and can also involve hydrogen bonds.

Why do hydrogen bonds form between water molecules?

Answers

Answer:

In water molecules the oxygen atom attracts the negatively charged electrons more strongly than the hydrogen. This gives water an asymmetrical distribution of charge so that it is a polar molecule. ... Because the water molecules are small, many of them can surround one molecule of the solute and form hydrogen bonds.

Explanation:

Final answer:

Hydrogen bonds form between water molecules due to the charge instability within the molecule caused by the difference in electronegativity between the oxygen and hydrogen atoms. These bonds lead to the unique behavior of water in its various states.

Explanation:

Hydrogen bonds form between water molecules due to the polar nature of a water molecule. The oxygen atom in water molecules is more electronegative, pulling the shared electron closer resulting in a slight negative charge. Conversely, the hydrogen atoms end up with a slight positive charge. These charges lead to a hydrogen bond when the slightly positive hydrogen atom of one water molecule is attracted to the slightly negative oxygen atom of another water molecule.

Hydrogen bonds are weaker than covalent or ionic bonds, but their large numbers in water lead to significant effects. They help maintain the liquid state of water at room temperature, among other unique properties. Hydrogen bonds aren't exclusive to water molecules; they can also be observed in DNA structure and protein formation.

Surface tension is caused by cohesion (the attraction of molecules to like molecules). Since the molecules on the surface of the liquid are not surrounded by like molecules on all sides, they are more attracted to their neighbors on the surface.
