9 Hydrogen Bonds Make Water Amazing

What is a Polar Covalent Bond?

A bond where bonding electrons are shared unequally between two atoms, resulting in partial charges.

What are Hydrogen Bonds?

Attractive forces between molecules or within the same molecule due to partial charges.

What properties of water are influenced by hydrogen bonds?

Cohesion, adhesion, surface tension, capillary action, solubility, chemical reactivity, thermal stability, and lubrication.

What is the role of water as a solvent?

Water is known as the universal solvent because many substances can dissolve in it.

Define Intermolecular Hydrogen Bonds.

Hydrogen bonds that occur between different molecules, such as in water.

Define Intramolecular Hydrogen Bonds.

Hydrogen bonds that occur within the same molecule, such as in DNA or proteins.

What does cohesion in water refer to?

The ability of water molecules to stick to each other due to hydrogen bonds.

What is capillary action in terms of properties of water?

The ability of water to move into small spaces without additional energy due to adhesion and cohesion.

Outline the four key characteristics of water due to hydrogen bonds.

Solvability, increasing chemical reactivity, thermal stability, and lubrication.

What is surface tension and how is it related to water?

The ability of water to keep its surface area to a minimum due to cohesive forces among water molecules.

Why is thermal stability important for water?

It makes it relatively difficult to change the temperature of water, which is essential for maintaining life.
