Witryna1) Determine if the base/Nu is strong or weak. If strong – SN2 or E2. If weak – SN1 or E1. 2) If it is a strong, bulky base – E2 only. If it is a non-bulky base, look further into the substrate – primary substrates do SN2, secondary and tertiary do E2 as the major mechanism. The effect of the solvent on nucleophilicity and basicity is ... WitrynaQ: 1. Identify whether the following substrates preferentially participate in the SN1 or SN2 reaction.….

(In all figures in this section, 'X' indicates a halogen … rythen7 3700xThe rate of an SN2 reaction is second order, as the rate-determining step depends on the nucleophile concentration, [Nu ] as well as the concentration of substrate, [RX]. r = k[RX][Nu ] This is a key difference between the SN1 and SN2 mechanisms. In the SN1 reaction the nucleophile attacks after the rate-limiting step is over, whereas in SN2 the nucleophile forces of… is finneas an irish nameWitrynaThe term SN2stands for Substitution reaction, Nucleophilic, 2nd order (also called bimolecular). According to the SN2 mechanism, there is a single transition state because bond-breaking and bond-making occur simultaneously.
