Carbon–nitrogen bond - Wikipedia
A carbon–nitrogen bond is a covalent bond between carbon and nitrogen and is one of the most abundant bonds in organic chemistry and biochemistry. [1] Nitrogen has five valence electrons and in simple amines it is trivalent, with the two remaining electrons forming a lone pair.
