To be neutral, nitrogen should have three bonds and one lone pair. A primary amine has two bonds to hydrogens, one bond to an alkyl group, and one lone pair (example: . A secondary amine has one bond to hydrogen, two bonds to alkyl groups, and one lone pair (example: . A tertiary amine has three bonds to alkyl groups and one lone pair (example: . In all of these, the nitrogen has three bonds and one lone pair, giving it a neutral charge.
