Open an introductory chemistry textbook. What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen bond? A hydrogen bond is an electrostatic ...

Textbooks currently define a hydrogen bond as a weak electrostatic interaction that forms between a lone pair of electrons on an electronegative atom and a hydrogen atom bonded to another strongly ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...

A hydrogen bond 1 forms between an electronegative atom (the acceptor) and a hydrogen atom covalently bound to another electronegative atom (the donor). Hydrogen bonds are of key importance in ...

A new catalyst for breaking the tough molecular bond between carbon and hydrogen holds the promise of a cleaner, easier, cheaper way to derive products from petroleum, say researchers. Simple, ...

The physicochemical and biological properties of hydrogen-bonded systems are significantly affected by nuclear quantum effects including zero-point energies of vibrational modes, proton delocalization ...
