    chloride and bromide ions toward the n-butyl and t-pentyl alcohols. We were able to analyze this by using refractometry to measure the amounts of alkyl chloride and alkyl bromide in each reaction. Experiment Scheme (Procedure A) To begin the experiment‚ we assembled a reflux apparatus in the fume hood with a 100 mL round bottom flask and a condenser. Next we added 44 mL of sulfuric acid to a 125 mL Erlenmeyer flask. We also measured 4.75g ammonium chloride and 8.75g ammonium bromide into a

    organic solution was dried with anhydrous sodium sulfate for a week. The liquid product was transferred to a 25 mL round bottom flask equipped with a stir bar and a simple distillation was set up. The solution was distilled and the density of the bromide was calculated at 1.222 grams/mL with a boiling range of 87-92◦C. The theoretical yield was calculated at 12.847 grams and the percent yield was 72.3 percent. Next was the characterization and assessment of the purity of the

    BROMINATION OF ACETANILIDE OBJECTIVE Aim of the experiment was too brominate acetaldehyde to form p-bromoacetanilide. INTRODUCTION Acetanilide is a chemical compound with the chemical formula of C6H5NH(COCH3). It is a crystalline solid that is prepared by acetylation of analine and is widely used in the dye industry. This crystalline solid is an odourless solid chemical that has a flake or leaf like appearance. It is also known as N phenylacetamide‚ acetanil or acetanilide. Its former
