In 1931, the Nobel Laureate Linus Pauling suggested that covalent bonds made from just a single, unpaired electron could exist, but these single-electron bonds would likely be much weaker than a ...

This, of course, poses quite a conundrum, as many believe single-electron chemical bonds can’t exist. That’s because all of the current known covalent bonds—where atoms connect by sharing ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

The discovery of a stable single-electron covalent bond between two carbon atoms validates a century-old theory. Covalent bonds, in which two atoms are bound together by sharing a pair of ...

Linus Pauling proposed the concept of one-electron covalent bonds in 1931, but direct evidence of their existence in carbon systems had proved elusive. Single-electron C–C bonds have ...

Atoms connected by covalent bonds are considered part of a single molecule, while those connected by hydrogen bonds can remain separate entities. So bonds in limbo between the two raise the ...
