The SN2 reaction - A Nucleophilic Substitution in which the Rate Determining Step involves 2 components. -SN2 reactions are bimolecular with simultaneous bond-making and bond-breaking steps. -SN2 reactions do not proceed via an intermediate. -SN2 reactions give inversion of stereochemistry at the reaction centre.

WebSince step 1 limits the overall rate of the reaction, the rate law for this step will be the same as the overall rate law. The predicted rate law for the overall reaction is therefore. \text {rate} = k [\ce {NO2}]^2 rate = k[NOX 2]2. This rate law is in agreement with the experimentally-determined rate law we saw earlier, so the mechanism also ... WebThis step is the rate-determining step of the reaction, and, because it involves only a molecule of the substrate, the reaction is unimolecular. The second stage of the reaction is the interaction of the intermediate carbonium ion with the nucleophile to give the products of the reaction. The unimolecular reaction is characterized ...
