What is hydrogen bonding? Under what conditions can hydrogen bonds be formed?Which pair of bonds has the strongest bond: C-N or C-O? Explain.Which pair of bonds has the strongest bond: C-H or O-H? Explain.Which pair of bonds has the strongest bond: C-...
Advanced theory of the hydrogen bond The hydrogen bond remains a fairly mysterious object in the theoretical study of quantum chemistry and physics. Most generally, the hydrogen bond can be viewed as a metric dependent electrostatic scalar field between two or more intermolecular bonds. This is slig...
Why is hydrogen important as a future clean energy source? A fuel is a chemical that can be ‘burnt’ to provide useful energy. Burning normally means that chemical bonds between the elements in the fuel are broken and the elements chemically combine with oxygen (often from the air). ...
They are unique because their structures, characterized by polymer chains, are linked through powerful hydrogen bonds that efficiently transfer mechanical stress. These characteristics make aramids perfectly suited to various industries like automotive, aerospace and defense, where heat resistance and ...
Building an investment portfolio may require personalization and finesse, but it can also be ultra-simple.

Hydrogen bonding is that the interaction involving a atom placed between a combine of alternative atoms having a high affinity for electrons; such a bond is weaker than an bond or bond however stronger than van der Waals forces. element bonds will exist between atoms in numerous molecule...
