Haloalkane reaction with ammonia
WebJun 4, 2024 · As per your guess an excess of ammonia when reacted with a haloalkane produces a primary amine via nucleophilic substitution. $$\ce{R-X + NH3 -> R-NH2 + HX}$$ But when the haloalkane is in … WebBecause of this, haloalkanes will undergo two key types of reaction. Nucleophilic substitution reactions. A halogen is substituted for another atom or group of atoms. The products formed when haloalkanes undergo this type of reaction are alcohols, amines and nitriles. Elimination reactions. A hydrogen halide is eliminated during the reaction.
