Ir Spectrum Lab Report

These RF values were valuable information, however they did not determine which solution an IR spectrum would be obtained for. This was determined by the strongest, or more visible spot on the plate. An error for this lab could have occurred at this point because the wrong spot was chosen. If the RF values were used to determined which spot to choose, results may yield a smaller presence of pure naphthyl ether and a larger presence of dichloromethane in the IR spectrum. The spot that is most visible on the TLC plate is the solution that needs to be chosen. For this lab, the forth sample was chosen because the spot showed up the most under the UV light. An IR spectrum was obtained for this sample, and peaks for dichloromethane and 2-naphthol were signaled.
These peaks show that the solution in vial 4 contained dichloromethane. This is viable because the column did contain dichloromethane, which is what the original 0.70 mL of the bottom layer solution was filtered through. Also the .7 mL of the solution that was ran through the column was a dried dichloromethane solution. The peaks that represented 2-naphthol, 1630 cm-1, 1364 cm-1, and 1216 cm-1, also showed that the solution in vial 4 contained 2-naphthol. This was determined by comparing the IR obtained with the IR posted for 2-naphthol. These peaks mean that 2- naphthol was present in the final solution. Indeed, 2-naphthol was present in the final solution because it was present in the dried dichloromethane solution. Also the pure product obtained in this lab, allyl 2-naphthyl ether, could have caused similar if not some of the same exact peaks as
