The SN2 reaction with 1 Butanol and sodium bromide and sulfuric acid. what is the major byproduct?
Experiment 14 SN2: Synthesis of 1-Bromobutane 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, nucleophilie, unimolecular) and S2 (substitution, nucleophilie, bimolecular). Tertiary alcohols follow the Syl route, primary alcohols follow the S2, route and secondary alcohols can follow either path. Sth CyHe 81 CH?
