If you prepared tert-butyl bromide by the procedure used for tert-butyl chloride, the product, and the aqueous solution would be so similar in density that you could not be sure which layer in the separatory funnel was a product to be retained, and which layer was aqueous acid to be discarded. How could you quickly decide whether the lower layer (first to be drawn off) should be discarded or saved?(It was a substitution experiment)

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...
