Experiment VI: Oxidation of Isoborneol with Bleach Purpose: In this experiment‚ Green chemical procedures were applied to oxidize isoborneol to camphor using bleach (NaOCl)‚ rather than the tradition chromium-based oxidizing reagents. The camphor was then purified using the process of sublimation. Procedure: Using a 50-mL Erlenmeyer flask‚ 1.316 g (8.5 mmol) isoborneol and 1.0 mL (17 mmol) glacial acetic acid were stirred vigorously with a magnetic stir plate. A volume of 1.7 mL NaOCl

strong odour in one of any of these soilds would simply mean that the molecules leave the surface easily. 10. From your answer to question 1‚ which of the two types of solids seem to have the stronger forces of attraction? Explain your answer. Camphor has a very strong odor which makes it easy for the particles in the soild leave it’s surface. The particle attraction to the soild is not very strong which means that the particles would leave the soild which then triggers a strong smell. 11. From

Green Oxidation of Borneol to Camphor Abstract: This lab converted borneol to camphor using a green oxidation. Sodium hypochlorite was used instead of the less “green” Jones reagent. Borneol was mixed with glacial acetic acid and oxidized with sodium hypochlorite to make crude camphor. The crude camphor was purified by sublimation. The final product was characterized by obtaining a melting point and inferred spectroscopy. The experiment was carried out to see if bleach could oxidize borneol

Keeping it Liquid Introduction: Phase changes within our world play a key role in how substances can be manipulated‚ and formed. A phase change is‚ “a change from one state (solid or liquid or gas) to another without a change in chemical composition” (Collins Italian Dictionary‚ 2016). Moreover‚ in this experiment‚ the use of tert-butanol was needed to perform phase changes. Tert-butanol is colorless oily with sharp odors‚ mixes with water‚ and has a freezing point of 78 degrees Farenheit (PubChem

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 should give one mole of camphorTheoretical yield of camphor = (1.305 mmol )( 152.23g mol-1)

The physical properties studied are odour‚ hardness‚ melting point‚ solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours‚ hard‚ a high melting point‚ soluble in water and insoluble in 2-propanol; some of the physical properties of camphor are a strong odour‚ soft‚ a low melting point‚ insoluble in water and soluble in

18th and 19th century‚ it became well known that chemicals such as camphor can induce seizures to help with mental illness.1 In 1934‚ a Hungarian psychiatrist‚ Ladislaw Meduna‚ empirically pursued his theory on the relationship between seizures and schizophrenia using camphor oil. He wanted to see if he could cure a patient with catatonic schizophrenia by inducing epilepsy in the patient through injecting the patient with the camphor oil. After several of these treatment sessions‚ the patient was reportedly
