Halogenoalkane to nitrile
WebThe halogenoalkane is heated under reflux with a solution of sodium or potassium cyanide in ethanol. The halogen is replaced by a -CN group and a nitrile is produced. Heating under reflux means heating with a condenser placed vertically in the flask to prevent loss of volatile substances from the mixture. The solvent is important. WebAnonymous1502OP. 20. sotor. i dont know the full mechanism as it isnt on my spec, but you dissolve the halogenoalkane and ammonia in ethanol. step one produces an ammonium salt which then reacts with another ammonia molecule in step two to produce an ammonium salt and a primary amine.
