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

On a TLC plate‚ capillary tube is used to transfer o- and p- hydroxyacetopheone‚ taking advantage of capillary force to make small spotting. A 30:70 ether acetate: petroleum ether is used as a solvent‚ which will not interact with surface of the silica gel due to a characteristic of non-polar. When they are desorbed‚ that is‚ when there is no interaction between the surface of the silica gel and the molecules of
