Since alkyl halides have positive charge on the carbon connected with Halogen they undergo nucleophilic substitution with NH3 which has a lone pair. R-X + NH3 → R-NH2 + HX, where R-alkyl and X-halogen. In case of excess of alkyl halide the reaction goes further to produce other amines: R-NH2 + R-X → R2NH + HX (secondary amine) R2NH + R-X → R3N + HX (tertiary amine) R3N + R-X → R4N+X- (quaternary ammonium salt)
