Identification of Unknown Organic Compound by Melting Point (M.P)‚ Boiling Point (B.P) and Infrared Spectroscopy Methods and Background The main objective of this lab is to identify the given unknown organic compounds with various methods. Identification of an unknown compound is important to perform through the process of melting point (M.P)‚ boiling point (B.P) and Infrared spectroscopy (I.R). Index of Hydrogen deficiency (IHD) and elemental analysis makes an experiment more efficient in

How It Is Synthesized Methamphetamine was first synthesized from ephedrine in Japan in 1893 by chemist Nagai Nagayoshi. In 1919‚ crystallized methamphetamine was synthesized by Akira Ogata via reduction of ephedrine using red phosphorus and iodine. Synthesis is relatively simple‚ but entails risk with flammable and corrosive chemicals‚ particularly the solvents used in extraction and purification; therefore‚ illicit production is often discovered by fires and explosions caused by the improper

Nucleophilic Substitution Reactions of Alkyl Halides 1. Summary of Experiment In this experiment we will be comparing the both SN1 and SN2 reactions using various compounds and sodium iodide and silver nitrate. We will be comparing the nature of the leaving group (Cl vs Br) in the 1-halobutanes as well as the effect of the structure

Exercise 1 Polymers – An introduction to Organic Chemistry Group 3 Jude Marchoni C. Tampus Meryl Marie Susan Chua Pearl Pontillas Paolo Pepito Gaia Casas I. Abstract: (Paolo) In this experiment we will be testing what would happen to the polymer when we add borax to it. A polymer is a compound made up of large molecules often in a solid state. Polymers are chemically formed by 100 to 10‚000 small molecules called "monomers". Monomers occur in molecular units or patterns

The Separation and Purification of Organic Compounds Sunshine Marie Introduction Each year‚ many thousands of new or unknown organic compounds are prepared or extracted from natural sources such as plants‚ fungi and animals. In order to identify an unknown organic compound or the components of a mixture of organic compounds‚ it is necessary firstly to separate and purify the compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient

Part 1. Hydrocarbon Nomenclature From International Union of Pure and Applied Chemistry (IUPAC) General Form of IUPAC Nomenclature [branching substituent(s)] Root [Suffix] Rules: 1. Identify the longest continuous chain of carbon atoms. This chain determines the parent name (root) of the alkane. The parent suffix for alkanes is‚ not surprisingly‚ -ane. For chains of equal length‚ pick the one with the most substituents. (Note: I number all possibilities going from left to right

Background The melting point of a compound is the temperature at which the solid is in equilibrium with its liquid. A solid compounds changes to a liquid when the molecules acquire enough energy to overcome the forces holding them together. A mixture melting point is useful in confirming and used to indentify an unknown compound‚ which we will be doing in this particular experiment. Purpose Measure the melting points of pure benzoic acid and pure mandelic acid. Determine the eutectic composition

Initially I was very much reluctant to take that class due to the subject bad stigma. I realize organic chemistry is honestly a puzzle. You have your starting material‚ which is your initial jigsaw piece ‚ and you add reactants‚ which are more jigsaw puzzle pieces‚ in order to create the picture that you want. Although certain pieces only fit with certain

asking yourself this question. “Should you buy the organic product or just the regular one?” People that support and follow the organic food industry say the food tastes better‚ is safer‚ healthier for you but when most are faced with the decision the price is just too much to overcome and empty your wallet for so people normally don’t go with the organic choice. One of the biggest problems are if you’re paying all of the money for organic food everyone would assume (or hope) that the quality
