what are some characteristics of hydrogen bond?
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.

The hydrogen bonds that form between water molecules account for some of the essential — and unique — properties of water. The attraction created by hydrogen bonds keeps water liquid over a wider range of temperature than is found for any other molecule its size.

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.

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.

Answer and Explanation: HH, which can also be written as H2, is not a hydrogen bond even though it involves two hydrogen atoms. H2 is a molecule in which two hydrogen atoms...

Intramolecular hydrogen bonding is the bond that takes place with hydrogen bonded in a single molecule i.e. within the molecule. Whereas intermolecular hydrogen bonding means the force of bonded hydrogens with two or more molecules.

Hydrogen bonding can occur between hydrogen and four other elements. Oxygen(most common), Fluorine, Nitrogen and Carbon. Carbon is the special case in that it only really interacts in hydrogen bonding when it is bound to very electronegative elements such as Fluorine and Chlorine.

A hydrogen bond is an intermolecular and intramolecular attractive force in which a hydrogen atom that is covalently bonded to a highly electronegative atom is attracted to a lone pair of electrons on an atom or a partially negative atom in a neighboring polar molecule.

Hydrogen bonding of water molecules Thanks to their polarity, water molecules happily attract each other. ... These attractions are an example of hydrogen bonds, weak interactions that form between a hydrogen with a partial positive charge and a more electronegative atom, such as oxygen.

1 Answer. 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. This is because oxygen is more electronegative than hydrogen.

Hydrogen bonds occur in inorganic molecules, such as water, and organic molecules, such as DNA and proteins. Van der Waals attractions can occur between any two or more molecules and are dependent on slight fluctuations of the electron densities.
