30 Ιαν 2023 · Why does a hydrogen bond occur? Since the hydrogen donor (N, O, or F) is strongly electronegative, it pulls the covalently bonded electron pair closer to its nucleus, and away from the hydrogen atom.

27 Σεπ 2024 · Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.
Hydrogen bonds are responsible for holding materials such as paper and felted wool together, and for causing separate sheets of paper to stick together after becoming wet and subsequently drying.
30 Ιαν 2023 · Hydrogen bonds can occur within one single molecule, between two like molecules, or between two unlike molecules. Intramolecular hydrogen bonds: Intramolecular hydrogen bonds are those which occur within one single molecule. This occurs when two functional groups of a molecule can form hydrogen bonds with each other.
Hydrogen bonds have about a tenth of the strength of an average covalent bond, and are being constantly broken and reformed in liquid water. If you liken the covalent bond between the oxygen and hydrogen to a stable marriage, the hydrogen bond has "just good friends" status. Water as a "perfect" example of hydrogen bonding.
23 Σεπ 2020 · A hydrogen bond is an attractive dipole-dipole interaction between a partially positive charged hydrogen atom in one molecule and a partially negative charged atom in the same or different molecule. As the name suggests, a hydrogen bond always involves a hydrogen atom, but the other atom can be any more electronegative element.
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.
