sulfanilamide was dissolved in the mother liquor‚ and also because of a small spillage of the crystals from the filtration step. Part C of this lab was performed by first finding the best solvent for Fluorene. This was done by testing water‚ toluene‚ and methyl alcohol by adding 6mL of solvent to .3g of Fluorene. It is then shaken‚ if it dissolves immediately like it did

Acetaminophen was found to be the second most polar analgesic drug tested. Acetaminophen contains a polar alcohol group on one side and amide group on the other but also includes non-polar functional groups that consisted of the benzene ring and methyl group. Acetylsalicylic acid low polarity results from only containing a carboxylic acid and ester and the presence of alkenes in the benzene ring. Ibuprofen was the least polar out of all analgesic drugs because it only contains one carboxylic acid

However‚ the formation of the oximes and various oxime products resulted in an incredible conformational inversion for the ethyl‚ isopropyl‚ and methyl systems. Furthermore‚ through the analysis of vicinal interproton coupling constants‚ it is believed that these compounds exist mainly in the diaxial chair conformation. To verify this‚ an X-ray crystallography was carried out‚ and the result undeniably

with potassium hydroxide in aqueous ethanol. The 3-chloro-3‚ 7-dimethyloctane will lose a hydrogen from three different carbons that cause the formation of three constitutional isomers. If the hydroxide ion attacks a hydrogen on the 3-methyl carbon‚ then 2-ethyl-6-methyl-1-heptene will be the product. If a hydrogen on the carbon-2 was attacked‚ then the product would be 3‚ 7-dimethyl-2-octene. If a hydrogen was attacked on the carbon-4‚ then 3‚ 7-dimethyl-3-octene will result (Figure 1).

international treaties aimed at eliminating the production and use of ozone-depleting substances‚ including chlorofluorocarbons (CFCs)‚ used as industrial refrigerants and in aerosols‚ and the pesticide methyl bromide. Specifically‚ developing countries need to focus on eliminating the use of methyl bromide as an agricultural pesticide and they must halt illegal trade in CFCs.
