what are the properties and characteristics of hydrogen bonds?
1664
A hydrogen bond is an intermolecular attractive force in which a hydrogen atom that is covalently bonded to a small, highly electronegative atom is attracted to a lone pair of electrons on an atom in a neighboring molecule. Hydrogen bonds are very strong compared to other dipole interactions.

H2SO4 and HNO3 are important strong acid molecules that can make strong hydrogen bonds in many surroundings. Especially, these molecules play a vital role under atmospheric conditions where heterogeneous reactions take place.

Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. ... In molecules containing N-H, O-H or F-H bonds, the large difference in electronegativity between the H atom and the N, O or F atom leads to a highly polar covalent bond (i.e., a bond dipole).

Water is the best-known compound that has hydrogen bonds. ... In summary, hydrogen bonds are (relatively weak) intermolecular forces, while covalent and ionic bonds are (relatively strong) intramolecular forces.

Structure and Chemical Properties of Hydrogen Fluoride Hydrogen fluoride is formed through covalent bonding (electron sharing) between a hydrogen atom and a fluorine atom. Hydrogen contains one electron, and fluorine requires one electron to become stable, so the bond forms readily when the two elements interact.

The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends.

The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water's properties of attraction.

Hydrogen bonds are formed between a hydrogen atom bound to a small, highly electronegative atom and another small, highly electronegative atom with an unshared electron pair. ... The nitrogen atom is called the hydrogen bond acceptor, because it is "accepting" the hydrogen from the oxygen.
