One of the key challenges in chemistry is to break and form bonds selectively in complex organic molecules that possess a range of different functional groups. To do this at the single-molecule level ...

Chemists at UCLA are showing that some of organic chemistry’s most famous “rules” aren’t as unbreakable as once thought. By creating bizarre, cage-shaped molecules with warped double bonds—structures ...

The latest short science news items from C&EN. An atomic force microscope (AFM) has revealed how the structure and bonding patterns of organic molecules change as they take on electrical charges ...

Chemical bonding “is the heart of chemistry,” according to Alexander I. Boldyrev, a chemistry professor at Utah State University who spends his time thinking about how molecules are put together. “But ...

The chemical bond is defined, and students learn to distinguish between ionic and covalent Introduction to Bonding: The chemical bond is defined, and students learn to distinguish between ionic, ...

Microscopy is advancing in leaps and bounds these days. It was just last week that scientists produced the first image of a hydrogen atom’s orbital structure. Not to be outdone, Berkeley chemists have ...

Boron, carbon, nitrogen and oxygen: these four elements can form chemical triple bonds with each other due to their similar electronic properties. Examples of this are the gas carbon monoxide, which ...

A chemical bond is the physical phenomenon of chemical substances being held together by attraction of atoms to each other through sharing, as well as exchanging, of electrons -or electrostatic forces ...

Illustration of intracluster bond formation, cluster containing two biomolecules, being exposed to UV light (left), causes a chemical bond forming between the two molecules (center), resulting in a ...
