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
A comparative study of polar/polar, covalent/covalent, and covalent/polar semiconductor superlattices is presented. Based on the calculated formation energy, charge density and electronic structure, the effects of the superlattice parameters on the overall properties (stability, quantum well structure, ...
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。

An example of a non-polar covalent bond would be carbon dioxide. The bond between two non-metals that have a relatively low electronegativity difference between the two elements leads to a non-polar covalent interaction. What is an example of a polar covalent bond? The bond between the hydroge...
A polar solvent like water is known to have a relevant influence on the covalent structure of polar molecules. This is clearly illustrated by the effect of hydration on the tautomeric equilibria of molecules. A prototypical example is the keto/enol equilibrium of β-diketones: whereas the enol...
Polar vs Nonpolar A compound may possess polar covalent bonds, but it may not be a polar compound. The reason behind it, due to the presence of net dipoles in a polar compound, they are asymmetrically arrayed. Take an example of water; it is a polar compound. They possess both a partia...
Polar vs. Nonpolar A compound can have polar covalent bonds and yet still not be a polar compound. Why is that? Polar compounds have a net dipole as a result of polar bonds that are arranged asymmetrically. This means that they have both a partial positive and partial positive charge that...
