Homework Answers
in structure 1 three tert-butyl group is present in equatorial position and hydroxy group and bromo group is present in axial position in stable conformation as shown below
in structure 2 all three tert-butyl group, bromo and hydroxy group present in equatorial position as shown below
5b.
epoxide will be formed when bromo and hydroxy group is present in anti periplanar orientations, it is present only in structure 1 therefore only structure 1 will produce epoxide

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...
