E. Reactions of Aldehydes and Ketones with Sodium Hydroxide Objectives: To know the reactions of aldehydes and ketones with sodium hydroxide a) State the function of Sodium Hydroxide in the test. Sodium hydroxide (NaOH) is the oxidizing agent. b) What are the principles involved in the test? What is its purpose? Cannizzaro reaction is a reaction that uses a strong base‚ such as sodium hydroxide‚ which results to the formation of a carboxylic acid (or its corresponding salt) and an alcohol

extraction technique. Then a crystallization was performed in order to separate benzoin by the use of hexane a solvent‚ leaving the dibromobenzne in the mother liquor. The percent recovery for benzoic acid was 91.8% and 80.3% for the benzoin. The MP for benzoic acid was 119-122°C (1) and 135-136°C (2)for the benzoin. The high percent recovery and closeness of measured MP to the literature value indicate that the designed procedure was successful. Results and Discussion: The initial sample consist

Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment‚ we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface

PurposeIn this experiment‚ sodium hypochlorite (NaOCl) in acetic acid mixture was used to oxidize emdo-borneol (an alcohol) to camphor (a ketone). The product would then be purified by sublimation and then be analyzed by Infrared spectroscopy and melting point test. Procedure and ObservationsPlease refer to the lab manual and the carbon copy attached. Data and CalculationsWeight of endo-borneol = 0.2013gNo of moles of endo-borneol = 0.2013g/154.25g mol-1 = 1. 305mmolSince one mole of endo-borneol

How does temperature affect the rate of reaction for Lipase? As the temperature increases‚ so will the rate of enzyme reaction. However‚ as the temperature exceeds the optimum the rate of reaction will decrease. I predict that at temperatures above 70°C the enzyme lipase will become denatured and at temperatures below 10°C the enzyme will become inactive. Since lipase operates within the human body I’d also predict that its optimum temperature would be around human body temperature which is approximately
