Synthesis of Butyl Naphthyl Ether by an Sn2 Reaction Gabriela Taginya, K7 TA: Stephanie Rosenbloom Wednesday, 1:25-4:25 !1 of!5 https://www.coursehero.com/file/21431792/Lab-Report-1-Sn2-CHEM-2510... / This study resource was shared via CourseHero.comPurpose The purpose of this lab was to perform the Sn2 reaction of 2-napthol and isobutane to yield butyl naphthyl ether. Using NaOH and ethanol, the product was isolated through reflux and vacuum filtration. IR Spectroscopy, melting point, and percent yield were used to characterize the product and evaluate the success of the experiment. Balanced Reaction Figure 1.
