NaI in acetone is normally used for halogen exchange reaction and it follows Sn2 mechanism. Since there was no reaction it was not a Sn2 mechanism. The mains reasons could be . 1) Cl is not a strong leaving group which can explain the reaction not taking place.

Witrynachoice of nucleophile used or even the solvent for the reaction. The S N2 Reaction (Substitution, Nucleophilic, Bimolecular) The S N2 type reaction is a one-step, concerted substitution process (make new bonds, break old bonds simultaneously). Both the alkyl halide and the nucleophile are involved (“bimolecular”) to determine the rate of ... WitrynaSo, my sample of 1-bromobutane reacted as expected. It was nearly immediate and didn't require me to heat it up. Br is a good leaving group and I- is a strong nucleophile, and the Sn2 loves a 1° alkyl halide. But my sample of 1-chlorobutane is confusing me. It didn't react until heated. Cl is a fairly decent leaving group. It's a 1° alkyl halide.

Witryna20 gru 2006 · Aprotic solvents are usually preferred for the SN2 reactions, because nucleophilicity and hence SN2 reactivity are severely retarded by the influence of the partial positive charge of protic solvents.
