drop wise; I had allowed the tap to run due to a confusion of the tap mechanism. The mixture therefore went up to 20 degrees and dropped gradually back to 11 degrees .After adding a little over 45mL of methanol‚ in order to start the process of recrystallization‚ my product was still cloudy. I feel I therefore may have added too much to re-dissolve the product. It took time for my product to break down over the steam and dissolve‚ yet eventually‚ suggested by the demonstrator I left it to become fully

Lab 3: Bromination of Acetanilide CHEM 2110 Hassan Alsaleh 0525970 Due date :11/02/2015 Q1: To find the limiting reagent we need to find the number of moles of acetanilide‚ and the number of moles of Bromine. Mass of Acetanilide used = 0.67g Molar mass of Acetanilide = 135.16g/mol[1] Number of moles of Acetanilide = (0.67g) / (135.16g/mol) = 0‚005 mols Volume of Bromine = 0.25ml Density of Bromine = 3.103 g/ml[2] Mass of Bromine = (0.25ml) X (3.103g/ml) = 0.78g Molar mass of Bromine

water. Completely dissolved in heat bath. Ones it was completely dissolved‚ and after the vacuum‚ the pure benzoic acid start to appear on top of the filtration paper with a pearl color. At the end of the ice bath the benzoic acid start the recrystallization. The purified and end product of the experiment was .20 grams of pure benzoic acid. Finally‚ the percentage recovered and purified benzoic acid was 40%. Based on this fallowing calculation .20 grams of benzoic acid multiplied

Coal is made largely of carbon but also features other elements such as hydrogen‚ oxygen‚ sulfur and nitrogen. Coal starts off as a plant matter at the bottom of water and is eventually covered and deeply buried by sediments where over time metamorphosis takes place. When peat is altered physically and chemically. This process is called “coalification.” During coalification‚ peat undergoes several changes as a result of bacterial decay‚ compaction‚ heat and time. Peat deposits are varied and contain

Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing
Premium Chemistry Chemical reaction Functional groups
Each grain of sugar is made of a small crystal that is made of an arrangement of molecules called sucrose. In a sugar crystal‚ the sucrose molecules are arranged in a pattern that extends in all three dimensions‚ and all of these molecules are attracted to each other by a type of interaction that binds molecules together called intermolecule forces. When you add granulated sugar to water‚ some of the sucrose molecules start separating from one another because they are attracted to the water molecules

not destroyed. The reaction can be observed as successful as 9-fluorenol is bright yellow‚ whereas 9-fluorenol is a white color. Approximately 100 mg of crude product is obtained through this experiment. Recrystallization occurs‚ however there is not one pure solvent that allows for recrystallization of 9-fluorenol. Thus‚ multiple solvents will be added together‚ water and methanol‚ the ratio of water to methanol must be determined for this to occur. Therefore‚ 1 mL of methanol will be added to the

Introduction Chemists often find a method to determine the level of “greenness” of a chemical reaction‚ or its “atom economy”. A higher atom economy is preferable because a greater amount of the reactants will be present in the product as opposed to the byproduct.1 A Suzuki reaction is classified as an organic‚ coupling reaction that includes boronic acid and a halide that are catalyzed by a palladium complex under basic conditions. Other palladium- catalyzed coupling mechanisms include the Heck
