In amines, nitrogen is bonded to three other atoms (alkyl groups or hydrogens) and has a lone pair of nonbonding electrons. This lone pair produces a region of electron density on the nitrogen atom, which coupled with the electronegativity of nitrogen produces a partial-negative charge at that location.

WebTertiary amines. In a tertiary amine, all of the hydrogens in an ammonia molecule have been replaced by hydrocarbon groups.
