Hydrogen bondingrefers to a weak bond formation between a hydrogen atom attached to a strong electronegative atom and another atom of higherelectronegativity. Hence, the hydrogen atom, which is connected to a highly electronegative atom (e.g., oxygen, nitrogen, and sulfur) via a covalent bond de...
A chemical bond in which a hydrogen atom that is already bonded to an atom in a molecule forms a second bond with another atom, either in the same molecule or in a different one. The second atom is usually of a type that strongly attracts electrons, such as nitrogen or oxygen. ...
A hydrogen bond tends to be stronger thanvan der Waals forces, but weaker thancovalent bondsorionic bonds. It is about 1/20th (5%) the strength of the covalent bond formed between O-H. However, even this weak bond is strong enough to withstand slight temperature fluctuation. But the Atoms...
Hydrogen bonds are not “true” bonds like covalent and ionic bonds, but rather directional electrostatic attractions between slightly negative and slightly positive atoms. The standard configuration of a hydrogen bond is of the type D— H···A where: H is a hydrogen atom with a partial posit...
A covalent bond refers to the chemical bond that is formed when atoms share electron pairs to reach a stable balance of attractive and repulsive forces by forming a full electron shell. This bond occurs from the electrostatic attraction felt by the nuclei of the atoms towards the same electrons...
A covalent bond is formed by sharing of electron pairs between same or distinct atoms. Sharing allows each atom involved to attain stability. A hydrogen bond occurs under specific condition, where a hydrogen atom which is already bonded to a highly electronegative atom (one of the three; ...
A hydrogen bond is the attractive interaction of a hydrogen atom with an electronegative atom, like nitrogen, oxygen or fluorine (thus the name "hydrogen bond", which must not be confused with a covalent bond to hydrogen). The hydrogen is covalently bonded to another electronegative atom. The ...
Covalent bonds and hydrogen bonds are primary intermolecular forces. Covalent bonds can occur between most elements on the periodic table. Hydrogen bonds are a special bond between a hydrogen atom and an oxygen, nitrogen or fluorine atom.
Hydrogen bondsare intermediate in terms of strength and length when compared tovan der waal's forcesandcovalent bonds. A hydrogen bond is mainly formed between a donor atoms such as an amine, which acts as a ligand, or a lewisbaseand acceptor atom likecarboxylic acid. The larger the number...
R. China. Hydrogen bond is a typical noncovalent bond with its strength only one-tenth of a general covalent bond. Because of its easiness to fracture and re-formation, materials based on hydrogen bonds can enable a reversible behavior in their assembly and other properties, which supplies ...
