Determine if each of the following statements is true or false 1 Larger atoms are better nucleophiles due to polarizability. 2 The identity of the nucleophile affects the rate of an SN1 reaction. 3 SN2 reactions proceed via frontside attack. 4 Bimolecular reactions tend to be stereoselective. 5 SN2 reactions invert all stereocenters in a haloalkane. 6 Cl-, OH-, and...

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?
