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...

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...

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 SNI (substitution, nucleophilic, unimolecular) and S 2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Syl route, primary alcohols follow the Sy2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Syl reaction involves rapid protonation of the alcohol, followed by...

Write a mechanism of the synthesis diisobutylene from tert-butyl alcohol with the use of elimination reaction. The following is the procedure of how it was done in the orgo lab: First of all, with the use of graduated cylinder 7mL of water was measured and then transferred in a 50mL round bottom flask. To the round bottom flask, it was added 7mL of sulfuric acid. The mixture was then cooled until the temperature got below 50 °C. In order to...
