Organic compounds {amine, organic}| can have carbon atom single-bonded to nitrogen atom: -C-N-. Amines are colorful, have pungent powerful odor, are slightly reactive, are polar, and are not oxidizable or reducible. Amines are liquids, except for ammonia gas. Amines are slightly basic if they have zero or one alkyl group, highly basic if they have two or three alkyl groups, and even more highly basic if alkyl group has double bond.
Amines {azide}| can have only three nitrogens.
A nitrogen atom can single-bond to a carbon atom and double-bond to a nitrogen atom, with only hydrogens on other bonds, in resonating structures {diazonium ion}.
A carbon atom can bind to three nitrogens, including one double bond, with only hydrogens bonded to nitrogens, in resonating structures {guanidium ion}.
Amines {piperidine} can have one non-aromatic ring with five carbons and one nitrogen atom.
Amines {pyrrolidine} can have one non-aromatic ring with four carbons and one nitrogen atom.
One carbon atom can double-bond to one nitrogen atom single-bonded to another carbon atom {Schiff base}: C=N-C.
