Why a Hydrogen Bond Is Not a Covalent Bond
Captions available
The idea
A hydrogen bond is an intermolecular attraction, only five to ten percent as strong as the covalent bond its name evokes.
In practice
Boiling every hydrogen bond out of liquid water leaves each molecule intact as H2O — no O-H bond breaks.
Where people slip
The name borrows "bond" from covalent bonding, but the two differ sharply in strength, the error Chem 1367 names.
