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‚ I calculated the

An individual would possibly feel completely lost without any direction‚ no starting point‚ and no help. That is a daily way of life for the illiterate. They become lost because of their lack of education at a young age‚ or because their parents did not give them the opportunity. This education is paid for by the government and

General Features of Oxidative Additions Oxidative addition reactions usually involve a coordinatively unsaturated 16-electron metal complex or five-coordinate 18-electron species‚ and take the general from: [pic] If the A and B ligands in the product are considered to be formally –1‚ then the metal center has increased its oxidation state by +2‚ and this is the origin of the name oxidative addition. Oxidative reaction can occur when a metal complex

Synthesis and Isolation of Expectorant Guaifenesin By: Ben DuBose Dr. Cossey 3361L Abstract The purpose of this experiment was to isolate and synthesize Guaifenesin. Isolation was performed with the use of two Guai-Aid Tablets‚ each of which contained 400mg of pure Guaifenesin. Reflux‚ a technique used to heat a mixture without evaporating the solution‚ was used to synthesize Guaifenesin through a Williamson Ether Synthesis reaction with an SN2 mechanism. Introduction

The carcinogenic nature of N-nitrosamines depends on the organs. For example‚ their targets for cancer in rodents include thyroid‚ pancreas‚ urinary bladder‚ trachea‚ lung‚ oral and nasal cavities‚ esophagus‚ kidney and liver. With respect to N-nitrosamides‚ skin‚ bone‚ peripheral nervous system‚ brain‚ small intestine and glandular stomach are targeted organs for cancers. Besides cancer‚ acute myelocytic leukemia and T and B cell lymphoma have also been triggered by N-nitrosamides. In table 8.1

Illiteracy in Our Society It was one of the days I will never forget in my life time. My father was very sick in Abeokuta; my village‚ where we both live together with my mother. The people in our community have tried their hand on one thing or the other to help him‚ but we are left with the only option of taking him to the hospital in the city. My mother is to go first to the city and inform my uncle about this incident‚ so that my uncle could help take my father to the hospital. Has my

Week 5 Essay # 3 Reading essay The Human Cost of an Illiterate Society by Jonathan Kozol rekindles the candle of the horrors of illiteracy within us‚ a candle that has been extinguished by our hectic lives. As he quotes James Madison’s statement‚ “A people who mean to be their own governors must arm themselves with the power knowledge gives”‚ these words make us think about ourselves and the society around us. A country is run by Government. That Government is chosen by people. And one third
