    Introduction: Pre-lab Questions Turn in typed responses in the beginning of lab. Answer in complete sentences. Show your work in pen where applicable. 1. What other compounds are extracted along with caffeine into the tea? Use what you know about the relative polarity of the functional groups within these compounds to determine the final destination of the following compounds: cellulose, tannins, chlorophylls, sodium carbonate. Do the majority of these compounds end up in the tea bag, filtered solid, aqueous layer,...

    If each bag of Lipton black tea contains 55 mg of caffeine, what is the maximum amount of caffeine that you could extract from one using our procedure? Assume one bag and 40mL of tea-water at the end of initial solid-liquid extraction. The partition coefficient (K) for caffeine in methylene chloride is 7.2. How much caffeine could be extracted using our procedure if we had used ethyl acetate (K = 2.0) instead of methylene chloride? Explain why the amount does...

    Introduction: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves because caffeine is more soluble in dichloromethane (140 mg/ml) than it is in water (22 mg/ml). However, there are...

    Experiment . the reduction of bencil (March 2020) Your name Sodium borohydride is a convert recent for the reduction of dehydes and ketones to 1" and 2 alcohols, respectively. The mechanism of the reaction - (below) is straightforward and is driven by boron's affinity for oxygen. In addition, given borohydride's remarkably low reactivity with OH groups under neutral and especially basic conditions, this reaction can be done in alcohol solvents. This means that (unlike LAH or Grignard reactions) no separate...

    Need help with number 2 and 3 on the postlab section. Elimination Reactions Background The purpose of this lab is to prepare an alkene by dehydration of an alcohol in the presence of an acid catalyst Elimination reactions often result in the formation of multiple products. In this lab, 2-methylcyclohexanol is dehydrated to form an alkene. The product will be analyzed by GC-MS to determine the ratio of alkene isomers formed. You will need to determine the mechanism of the...
