13 Νοε 2022 · Identify three special properties of water that make it unusual for a molecule of its size, and explain how these result from hydrogen bonding. Explain what is meant by hydrogen bonding and the molecular structural features that bring it about.
27 Σεπ 2024 · Because of its extensive hydrogen bonding, water (H 2 O) is liquid over a far greater range of temperatures that would be expected for a molecule of its size. Water is also a good solvent for ionic compounds and many others because it readily forms hydrogen bonds with the solute.
Hydrogen bonding between water molecules (intermolecular forces) explains many of the unusual properties of water, including high cohesion and adhesion, high surface tension, high specific heat and heat of vaporization.
Water's polarity makes it an excellent solvent for polar substances and ions, facilitating chemical interactions within cells.

27 Αυγ 2022 · H-Bonds and Water. H-bonding occurs in water. In the liquid state they are rapidly being formed and broken as the mobile particles move over each other.
22 Ιουλ 2022 · Water is an amazing solvent, and has remarkable physical and chemical properties that make it the essential ingredient to life as we know it. The special properties of water come from the fact that the elements hydrogen and oxygen have differing electronegativities.
In water, the hydrogen bond occurs between the oxygen of one molecule and the hydrogen of another. These bonds result in important properties in water such as cohesion (the ability for water to stick to itself), adhesion (the ability for water to stick to other molecules), surface tension, high specific heat, and its solvent properties.
