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。
Types–Single bond, double bond, triple bond,(depending on sigma and pi bonds involved) Covalent bond vs. Hydrogen bond As the name implies, a hydrogen bond is a chemical bond wherein hydrogen serves as a bridge between two atoms. Similar to a covalent bond, the hydrogen bond is a common...
ionic, covalent, polar covalent, metallic, hydrogen 这五种Bond 键的强弱由大到小排列,急求,谢谢。 如题,谢谢。 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
partially positively charged hydrogen atom forms a bond with the other electronegative atom. This bond is called as hydrogen bond and is weaker than covalent bond.For example, in HF molecule, the hydrogen bond exists between hydrogen atom of one molecule and fluorine atom of another molecule as ...
Imine ExchangeHydrogen Bonding CatalysisDynamic SystemsSolid-Supported CatalystThe reversibility of imine bonds has been exploited to great effect in the field of dynamic covalent chemistry, with applications such as preparation of functional systems, dynamic materials, molecular machines, and covalent ...
When the two atoms of the diatomic molecule are the same (e.g. two hydrogen atoms), the electron density is distributed symmetrically between the two nuclei, and the covalent bond is homopolar. If the two atoms are not the same, the electron distribution will be asymmetrical, and the ...

A hydrogen bond is: A. a covalent bond between molecules that contain H bonded to F, O, or N. B. a covalent bond between water molecules. C. a dipole-dipole attraction between molecules that contain H bonded to F, O, or N. D. an ionic bond betw...
In the case of H2, the covalent bond is very strong; a large amount of energy, 436 kJ, must be added to break the bonds in one mole of hydrogen molecules and cause the atoms to separate: H2(g)→2H(g)ΔH=436kJH2(g)→2H(g)ΔH=436kJ Conversely, the same amount of energy is ...
Hydrogen bonds are another noncovalent bond. It is a type of attraction force between two atoms of two different molecules which is a weak attraction force. However, when comparing with other types of intramolecular forces such as polar-polar interactions, nonpolar-nonpolar interactions like Vander ...
