luction Nucleophilic substitution is a tremendously useful and important reaction in organic chemistry. No s it used extensively in organic synthesis, but some biochemical processes also proceed via nucleophili Litution mechanisms. Often, nucleophilic substitution is one of the first organic reactions covered and it efore very important to understand it thoroughly. This experiment investigates the relative nucleophilicity of chloride and bromide ions. Also of interes ow varying the degree of substitution at the electrophilic center affects the reaction mechanism. The...
#1-6 1. Outline a separation scheme for isolating caffeine from tea. Use a flowchart similar in format to that shown in Technique 2, Section 2.2. 2. Why was the sodium carbonate added in Experiment 13A? 3. The crude caffeine isolated from tea often has a green tinge. Why? 4. What are some possible explanations for why the melting point of your isolated caffeine was lower than the literature value (236°C)? 5. An alternative procedure for removing the tannins and gallic...
Create a separation scheme flow chart/diagram to isolate methyl salicylate from a product mixture containing the following: Methyl salicylate, methanol, concentrated sulfuric acid. Lab procedure for separation: Extract with 25mL dichloromethane. Drain the bottom organic layer into a beaker. Repeat the extraction with another 25mL portion of dichloromethane, isolate the bottom layer, and then combine it with the first dichloromethane extract. Pour the combined extracts back into the funnel and wash the solution with 25mL of water. Drain the lower...
