WebHere, I will invoke the Hammond postulate to convert a thermodynamic argument into a kinetic one. First, we establish that the S N 1 mechanism proceeds via an intermediate cation. This intermediate is, importantly, higher in energy than the reactants. Second, the first step of the S N 1 reaction is the slow step and therefore (given the first ...

WebThe haloalkanes are attacked only slowly by water. The rate is much faster, but a poor yield is obtained if the haloalkane is refluxed with aqueous sodium or potassium hydroxide. b) Formation of nitriles: attack by CN -. If a haloalkanes is refluxed with an alcoholic solution of KCN, an acid nitrile is formed: R-C=N. C2H5Br + CN- → C2H5CN + Br-.
