The purpose of the experiment was to examine the reactivity’s of several different substrates under SN2 reaction conditions. Discussion: All of the SN2 reaction mechanisms react the exact same way. The nucleophile sodium iodide attacks the delta positive alpha carbon forming an intermediate that has a partially formed C-I bond and a partially broken bond between carbon and the delta negative leaving group. The stereochemistry is inverted at the alpha carbon as the C-I bond fully forms. Then…

needs help, and that this school is about QUANTITY NOT QUALITY. Your education, your future, is put into their hands when you decide to come here. Again if you are the type of person who likes to read, like to teach THEMSELVES material, such as chemistry and biology, then this school is for you. But if you feel that you are going to need assistance for anything, then CONSIDER ANOTHER…

Data Calculated from Experiment Solid-Liquid Weight (g) Solid-Liquid % Recovery Liquid-Liquid Weight (g) Liquid-Liquid % Recovery Acid 0.01 20 % 0.028 56 % Phenol 0.011 22 % 0.001 2 % Amine 0.013 26 % 0.005 10 % Neutral 0.03 60 % 0.026 52 % Table 1 shows the data obtained from this experiment of both the solid-liquid extraction (on the left side of the table) and the liquid-liquid extraction method (on the right side of the table). It shows that in the solid-liquid extraction, most of the…

I want to be a part of the NSF-REU program because I know I would make a great contribution. In an informal research project for my biology lab course, I led a team of four in a time-crunched, self-created lab. I took up the role of leadership, assigned tasks, organized meetings and worked outside of class hours to complete the testing. Taking charge wasn’t always easy for me but, at the College of Saint Benedict, there is a NSF S-STEM scholarship program called FoCuS. The program provides…

was separated using microscale separation of acidic, basic, and neutral components by liquid/liquid extraction. Liquid/liquid extraction is a very common method often used in work-ups and allows for isolation of neutral components using acid/base chemistry; this method is extremely helpful in separating reactants and products of a synthesis. The components were purified and dried by evaporation and vacuum filtration. The separated compounds were then classified by determination of their melting…

Aeshah Alrubayyi CHM 643 Reactive intermediate has been important investigated in physical organic chemistry. It classes to carbocations, carbenes, carbanions and free radicals. Recently, observable intermediate classified as reactive, and an unobservable intermediate is kinetically when occurs at a branch point in a mechanism. A reactive intermediate is formed in the rate determining step of a reaction and then goes to give products in low barrier. Also, the hydrocarbon reaction of terminal…

studied for more than hundred years before that of transition metals. The structure of organometallic compound of transition metals looks very similar to the coordination compounds in physical and chemical properties but in actual these are much more organic as compared to coordination compounds. Some major differences in properties are: Properties of typical coordination compounds Properties of typical organometallic compounds Water-soluble High-melting solids (. 250°C) Air-stable…

In the chemistry universe we have many different tools to differentiate and to help identify a substance. The smallest particle of matter is the atom. An atom has the same chemical particles as a whole sample of the element. Everything in the world is made up of these tiny particles called atoms. Growing on our knowledge of the atom, if you combine two atoms chemically you produce a compound. The two different classifications of compounds include organic compounds or those that contain carbon…

post-secondary education majoring in chemistry. After graduating, Carothers continued his studies as an organic chemists. He went on to earn a Master's degree and a Ph.D. Carothers was interested in electronic theory of valence, explaining how atoms bonded together. In 1924, Carothers wrote a paper on electronic natures of the carbon-carbon double bond for the Journal of the American Chemical Society. It sparked his interest in theoretical and experimental chemistry. Shortly after February 6th…

trend but my thought process was quite dissipated since I get admitted department of pharmaceutical science at the University of Dhaka, best institution of Bangladesh. During my undergraduate studies, I gained comprehensive understanding of organic chemistry for two years with sophisticated laboratory experience. This subject gives me the basic idea about chemical process inside biological system. In addition to this, mandatory two years course of Physiology helped…
