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 new 3D complex [Mn(bpe)(H2O)4]0.5n(tp)0.5n(bpe)n [bpe = 1,2-bis(4-pyridyl)ethane, tp = terephthalate] with long-distance antiferromagnetic interactions clearly shows that hydrogen bonds are useful in increasing molecular dimensionality and the bpe ligand favors crystal packing due to its...
A hydrogen bond is weaker than an ionic bond or a covalent bond, but stronger than van der Waals forces. Hydrogen bonds play an important role in biochemistry and produce many of the unique properties of water. Hydrogen Bond Definition
一般来说，考虑到破坏化学键所消耗的能量，有以下顺序：ionic> polar covalent> covalent> hydrogen.而金属键metallic的强弱不好判断，相关理论解释也很负责，故一般不参与比较。
One of the major distinctions between a covalent bond and a hydrogen bond is theelectronegativityof the atoms involved. In a covalent bond, the electronegativities of the two atoms are comparable. Conversely, hydrogen bond forms when the slightly positive hydrogen atom of a polar covalent bond fo...
noun a type of chemical bond in which a hydrogen atom that has a covalent link with one of the electronegative atoms (F, N, O) forms an electrostatic link with another electronegative atom in the same or another molecule.Compare Meanings hydrogen bond vs. ionic bond Click for a side-by-...
A Strange Chemical Bond: A Hybrid of Hydrogen and Covalent BondsYang LiuLongdom Publishing SL
What Is a Hydrogen Bond? 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...
