The redox reactions affect the number of covalent bonds that a carbon makes to a heteroatom substituent, such as nitrogen and oxygen. Each redox state of carbon (Fig. 2) is associated with a class ...

This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms form a double bond because there is a strong enough attraction in both directions and room for the ...

The alkanes are a homologous series with a structure based on a carbon chain - each carbon atom forms four covalent bonds The intermolecular forces vary between molecules, so different organic ...

Carbon nanotubes are essentially a sheet of graphene rolled up on itself. To join a nanotube with other molecules, it is possible to do so directly by covalent bonds which break the tube a little ...

Organometallic compounds of actinides like berkelium typically have higher symmetries and form more covalent bonds with carbon, making them more useful for observing the unique electronic structures ...

These bonds impart exceptional chemical stability and extended π-conjugation to sp²-carbon conjugated 2D polymers ... which rely on dynamic covalent chemistry such as C=N linkages, have proven ...
