    3-decanol‚ toluene will have a higher Rf value than benzoic acid‚ and cyclooctane will have a higher Rf value than cycloctanone. This is because they are not as polar as the compounds with lower Rf values‚ the compounds that are most polar tend to stay longer with the polar adsorbent‚ while the least polar compound travels with the eluent that is lower in polarity. 2. TLC in today’s experiment stands for Thin Layer Chromatography. 3. From least polar to the most polar: Heptane-Toluene-Acetone-Methanol-Acetic

    Results and Discussion – Expt. 3 (Crystallization) Name: Parts A and B: 1. Please comment on the relative purity of your recrystallized salicylic acid (Hint: You should use your empirical data to support your claim). -The Salicylic acid that I obtained had a melting point range around 157-158 degrees Celsius for Part A. For Part B the melting point range was 156-157.5 degree Celsius. Part B‚ I would say the sample is less pure because of the notion that impurities lower the melting point

    purpose of this lab is to synthesize Lidocaine from 2‚6-dimethylaniline‚ using diethyl amine‚ 2-chloroacetyl chloride‚ acetic acid‚ and toluene. The Lidocaine was made by adding 2‚6-dimethylaniline to 2-chloroacetyl chloride in acetic acid. Sodium acetate is added in order to make the compound soluble. The product is dried‚ then treated with diethyl amine and toluene. This is refluxed using a water-cooled reflux condenser. The vapor is condensed by the cold water as the compound is being heated.
