4) Can you ever have only SN2 or only SN1?
Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the leaving group departs with both electrons of its bond to...

Nucleophilic Substitution Reactions Lab (SN1 and SN2 reaction mechanisms) Below are my lab results for SN1 and SN2 reactions. This first column of the chart gives the ten starting material halides used in this experiment. The second column gives the reaction time for SN1 mechanisms with silver nitratate in ethanol solution. The third column gives the reaction time for SN2 mechanisms with sodium iodide. In theory, primary alkyl halides are expected to react faster in SN2 mechanisms, and tertiary alkyl...

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...
