    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...

    In our experiment we will use three different substrates: 1°, n-butyl chloride; 2°, sec-butyl chloride; and 3°, tert- butyl chloride, and we will evaluate their reactivity and the rate of the reaction in an SN1 reaction. We will use an acid-base indicator to monitor the completion of the reaction and a salt, silver nitrate, to obtain a precipitate. The success of the reaction is evidenced by the change in color of the indicator (from orange to red) due to the...
