Haloalkane reaction with ammonia
WebReaction details and products. The halogenoalkane is heated with a concentrated solution of ammonia in ethanol. The reaction is carried out in a sealed tube. You couldn't heat … WebMar 3, 2024 · In the nucleophilic substitution reaction of haloalkanes with ammonia, instead of sharing it's lone pair with the carbocation, ammonia loses one of it's hydrogen and forms a primary amine, and the lone pair remains on the nitrogen. I can't understand why it is so. Why can't the nitrogen bond with carbon, it'll still have a fully filled octet.

WebMar 30, 2024 · Secondary haloalkanes can react with ammonia via \[{S_N}1\] or \[{S_N}2\] reaction mechanism, mostly \[{S_N}1\] is favoured, as it is quicker than \[{S_N}2\]. As the size of the halogen atom increases the rate of reaction increases (as you go down in group 17), because the bond enthalpy of the C-halogen bond decreases which means it is at ...
