Organic chemistry Essays

decades, electronics coupled with organic chemistry has been an area of great research interest, especially in physics and chemistry. Until a few years ago, this topic was thought to have no practical approach and was believed to be just research-oriented. Modification of chemical structures so that they can in a way enhance the properties of these when used for electronic applications- especially as a thin film has gained major impetus. It was always thought that organics would soon replace the semiconductors

I first met my friend in Calculus 2 in my sophomore year. His major was biochemistry, just like mine, so we ended up taking other classes together. In General Chemistry 2 lab, we were lab partners. We helped each other out on the long and tedious process of writing lab reports. The Organic Chemistry 1 lab was a little better, but still long with many failures and repeats of experiments. Despite the struggles, we had fun in the lab too, like in the experiment where we had to extract the fragrance

atomic weight of 200.59 u, oxidation states 0, +1 and +2. Is a liquid and volatile metal soluble in water to some extents? In the oxidation states +1 and +2 is able to form organic compounds of type RHgX and R2Hg where R can be alkyl- or Aryl groups. The RHgX compounds properties depend on the nature of the X rest; If the organic compound contents hologenides the result is a highly lipophilic compound whereas If the rest is oxygen anion, chemically stable, thermally labile and light sensitive compounds

Excess molar volumes were measured at 308.15K as a function of composition by a direct dilatometer method for binary liquid mixtures of 4-methylpentan-2-ol + n-hexane, + n-heptane, + n-octane, + n-decane and + n-dodecane. All the mixtures exhibit positive excess volumes over the whole mole fraction range. VE results of 4-Methylpentan-2-ol with n-alkanes were compared with VE of Hexanol-1 + n-alkanes. The variation of VE with the change in the position of either alkyl group or –OH group is discussed

In organic and inorganic chemistry, nucleophilic substitution reactions are the most well studied and useful class of reactions. These reactions can occur by a range of mechanisms, the two studied in this lab are the SN1 and SN2 reactions. In a nucleophilic substitution, the nucleophile is a electron rich chemical species which attacks the positive charge of an atom to replace a leaving group. Since nucleophiles donate electrons, they are defined as Lewis bases. The positive or partially positive

In the talk, “Adventures in Organic Chemistry – Over Three Decades of Synthetic Organic Chemistry” presented by Dr. Chris Condeiu, he tried to relate the industry of organic chemistry to a students’ perspective. Three major points were drawn out through the talk. The first was the perspective of how capitalism drives the industry and the mechanism of doxycycline was formed. With an overview of his talk, the expectation was that a deeper understanding of how pharmaceutical drugs’ mechanisms are formed;

Organic chemistry II Experiment 3: chromic acid oxidation reaction Introduction: Camphor is very compact and its molecular structure is symmetrical which gives it the property to change directly from a solid to vapour when heated. Therefore, camphor can easily be purified by sublimation technique. Sublimation is a phase change in which a solid phase passes directly into the vapour without going through an intermediate liquid phase. Solids which have vapour pressure below melting points can be purified

At the start of my freshman year of college, I decided to dive straight into organic chemistry. Having a preview of the subject in a special offered course at the end of my senior year of high school intrigued me and I wanted to learn more. Despite academic advisors telling me I would struggle and possibly fail at taking such a notoriously difficult class at the beginning of my academic career, I felt confident in my ability to take it and be successful, and I was right. During the second part

I was enrolled in Bio 1108, English 1102, Power Stretch and Organic Chemistry. Due to financial issues dealing with my parents having marital troubles I had to focus on getting money and had to drop my English 1102 class. This was done before the withdrawal date. I continued with my other classes because I thought I had these unforeseen circumstances under control. I continued the semester taking my biology 1108 and organic chemistry. The problem later began to escalate where I thought I had to

Answer # 1: Oxidizing Agent: An oxidizing agent is a substance that oxidizes some other substances and gains electrons. Oxidation is basically a gain of oxygen. Oxidizing agents give oxygen to other substances. Oxidation is also defined as loss of hydrogen. Let consider an example: CH3CH2OH CH3CHO Reducing Agent: A reducing agent reduces other substances and loses electrons. Reduction is basically a loss of oxygen. Reducing agents remove oxygen from other substances. Reduction

Chemistry Exploration Topic: determining the activation energy of a chemical reaction Research Question: What effect does temperature of the chemical reaction have on the activation energy ? ICT: Microsoft Word Autograph Microsoft Excel Introduction This experiment is designed to help in estimating the activation energy of the rate-limiting step in the acid catalyzed reaction of acetone with iodine. This is achieved by measuring the reaction rates at different reaction temperatures over

from the 1800’s. Dr. Wöhler was alive in a period where chemistry was separated into two different areas; Organic Compounds and Inorganic Compounds. At the time, Organic compounds (chemicals generally derived from plants or animals) were viewed as less stable, and formulas were difficult to ascertain from elemental analysis. Whereas, Inorganic Compounds were easier to “deal with” scientifically. Inorganic Compounds followed the laws of chemistry and were easy to synthesize and analyze. (Ramberg, 2000)

Career Exploration Fields: Organic chemistry is the study of carbon-based molecules. These chemists are called organic chemists and work with substances found in living things, such as plant and animal material. Modern organic chemists, however, have expanded the field to also encompass non-organic compounds. Not only do they transform organic compounds into new compounds not found in nature, they also synthesize non-organic compounds into synthetic organic compounds by separating molecules and

Dr. Condeiu’s presentation on synthetic organic chemistry was a rewarding experience because he touched on some very important concepts. Not only did he mention many of the things discussed in class in terms of real world examples, but he also brought a human face to being a synthetic organic chemist, and also mentioned several examples of synthetic challenges he has personally faced. Dr. Condeiu showed some real life examples of themes we discussed in class. In particular, I found his example

Samarium (II) Iodide A single electron transfer reagent useful for organic synthesis. A look into samarium (II) Iodide (Sml2), a powerful single electron donor which plays a vital role in the chemoselective reduction of certain functional groups and carbon-carbon bond formations. Cathal McKenna Student Number: 11322441 10/6/2014   Introduction Samarium (II) Iodide has emerged in recent times as a very useful reagent in organic synthesis. The compound was first used by Kagan and his researchers

Endless numbers of extraordinary content and theories in chemistry continue to interest me and have fuelled me to research further into my current studies in addition to extra-curricular reading around the subject. Chemistry holds many unique qualities; for example the ability to calculate the number of particles of air present in any room given the room volume and standard conditions. I personally find this hugely intriguing especially with the knowledge that there are likely to be approximately

In the main quadrangle, I struck up a conversation with a UChicago student. When I asked him what he was majoring in, he said with a completely straight face, “Religious Studies and Astrophysics”. While other institutions might satisfy one of my interests, UChicago can satiate them all. I’ve always been curious, which unquestionably translated into a love for discovery. Instead of wanting dolls for my birthdays, I asked for Legos or 1000-piece jigsaw puzzles. Walking through Best Buy, I’ve always

Hi Dad How is it going? My first semester at the University of Michigan is very exciting. One of my favorite classes is the organic chemistry lab. It is completely different from the typical Orgo lab that you took at college. The instructors are trying to teach us the applications of chemistry in real life. Indeed, we, as students, are even creating our own experiment and testing our own hypothesis. This week, my group’s experimental goal was to convert an inactive prodruge to an active drug. You

Lab Report 10: Nitration of Bromobenzene Raekwon Filmore CM 244 Section 40 March 27, 2018 Introduction: For this experiment, nitration of bromobenzene was the focus of the lab. The benzene is an aromatic compound and when it reacts with wither a mixture of sulfuric acid or nitric acid creates what is known as a nitro group. The formation of the nitro group is possible because it is an electrophilic aromatic substitution reaction. The creation of the nitronium ion is shown below: The reaction

Kolbe-Schmitt Reaction Kira Wall (CHE433) 12-3-14 The Kolbe-Schmitt reaction is named after Hermann Kolbe and Rudolf Schmitt. Schmitt published his research in the Journal fur Pracktische Chemie in 1885 while Kolbe published his research in the Annalen der Chemie und Pharmacie in 1860. The reaction adds a carboxyl group onto the benzene ring of a phenol. The process uses a base carbon dioxide and acid work-up. The original reaction done by Kolbe involved the formation of sodium phenoxide
