Hydrogen Bond

Hydrogen Bond

A hydrogen bond is a weak attraction that forms between a hydrogen atom, which is covalently bonded to a highly electronegative atom (such as oxygen, nitrogen, or fluorine), and another electronegative atom in a nearby molecule. Although weaker than ionic or covalent bonds, hydroge...

Hydrogen bonds are fascinating forces that occur between molecules. But what exactly are they, and why do they matter?

Imagine a water molecule made of one oxygen atom and two hydrogen atoms. The oxygen atom pulls shared electrons closer to itself, creating a slight negative charge on its end, while the hydrogen ends become slightly positi...
