isopentyl alcohol. After refluxing there is an isolation procedure where excess acetic acid and remaining isopentyl alcohol are easily removed by extraction with sodium bicarbonate and water. The ester is then purified by simple distillation and the IR is then obtained. Techniques and equipment used throughout the experiment include a reflux apparatus‚ separatory funnel for isolation‚ vacuum filtration‚ and simple distillation. The reflux condenser is used to allow thorough distillation of the

Experiment H: Identification of an Unknown Organic Compound The objective of this lab was straightforward. We were given an unknown compound and we were to perform an IR spectroscopy and as well as NMR spectroscopy. With the IR spectroscopy‚ I was able to name the functional groups I have on my compound and further confirmed my assumptions by looking at the NMR spectroscopy after. The unknown number I was given was number 203. The molecular weight of the compound was 121. From the molecular weight

be extracted from cloves by using the method of steam distillation. The extracted compound will then be separated from the water using methyl chloride‚ which will then be evaporated using a rotary evaporator leaving only the essential oil‚ Eugenol. IR spectroscopy will be used to determine the structure of the extracted compound. Results and Discussion Four samples of Eugenol were combined to be analyzed for the final product. A lower percent recovery‚ as indicated by Table 1 could be due to the

The NFL‚ as a “professional football league‚” is listed under the code section §501(c)(6) statute‚ in the same class as business leagues. The forerunner to code section §501(c)(6) “business leagues” was enacted as part of the Tariff Act of 1913. It’s assumed the U.S. Chamber of Commerce request for an exemption for nonprofit civic and commercial organizations from this passage. There were only seven hundred and fifty business leagues when the code section §501(c)(6) exemption was first enacted as

1-49 Case Study Problem An audit by the IRS was done on Mr. John Gemstone‚ a wealthy client. A few deductions were questioned‚ such as; $10‚000 loss on beach rental‚ $20‚000 charitable contribution‚ $15‚000 loss for operation of cattle breeding ranch. There was a concern that the battle breeding ranch is not a legitimate business‚ which is more like a hobby. My supervisor was asked that I represent Mr. Gemstone in his discussions with the IRS. In order to get elaborate more on Mr. Gemstones deductions
