Test tubes 2. Welcome to BrainMass. Because of the number and variety of hydrocarbons that can exist, some means They are extremely important to our society because so many products are derived from them: fuels, fabrics, plastics, antifreezes, anaesthetics, insecticid es, to name a few. HYDRO C ARBONS 2. Gas Chromatography data is attached to the back of lab report. Stirring rod 3. Using Experiment 11 – Identification of Hydrocarbons Discussion The number of known organic compounds totals into the millions. Lab Report Analysis Of Hydrocarbons. Test tube rack Objectives Study the physical and chemical characteristics of some hydrocarbons. An acetylene torch takes advantage of the high heat of combustion for acetylene. Hence, this experiment is a success. conclusion for hydrocabon's structure and chemical structure. All hydrocarbons will burn in the presence of oxygen (in the air). Benzene, C 6 H 6, is the simplest member of a large family of hydrocarbons, called aromatic hydrocarbons. Reaction of hydrocarbons with bromine: Bromine is a reddish brown liquid, so if it reacts with another chemical, the initial red color will disappear (or at least fade). The reaction is catalyzed by the addition of base or acid to the reaction. Procedure Solubility 1. Here is an example of a combustion reaction: C 3 H 8 (g) + 5 O 2 (g) à 3 CO 2 (g) + 4 H 2 O (g) + heat Combustion reactions also give off a great deal of heat. Conclusion: Our unknown originally was orange with addition of bromine, but after a few minutes of sitting it turned clear. Lab 2.doc; Solution Preview. Eyedropper 4. This test is non-speci c and will give a positive result for a variety of compounds (including alkenes and alkynes as seen in Experiment 21). Hydrocarbons 1. A. Let's see if I can help you interpret the results of this experiment, one part at a time. The reaction of acetylene with bromine is a typical example: Acetylene and the other alkynes also burn readily. CHM1024 Report 3 : Identification of Hydrocarbons. A general test for oxidation of compounds is by reaction with Potassium Permangate. CONCLUSION In this experiment, the properties and the difference between an alkane and alkene is identified. Hydrocarbons are organic compounds that contain only carbon and hydrogen. By: Josseline Fonseca Materials 1. This is expla ined because equation 4 actually did occur without a catalyst, but intsead with free radical bromines being formed as light was exposed to the bromine thus bromination occurred on our benzylic ring. Tutorial_3_Questions (1) DIscussion of Reactions of Halides in Solution. 6 November 2012 SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports.Three fields of study are composed within this memo that includes Electrical Engineering, Environmental Engineering, and Petroleum Engineering. Aromatic Hydrocarbons. Of these compounds, the simplest types are those that contain only hydrogen and carbon atoms. Make a comparative study of the properties of some petroleum derivatives. This reaction is called combustion, and the products of this reaction are water and carbon dioxide gas. CONCLUSION/ DISCUSSION: In this experiment, the main purpose is the oxidation of an alkene to an alcohol is investigated via the in situ formation of the corresponding trialkylborane, followed by the oxidation of the carbon-boron bond with hydrogen peroxide. Question: REPORT SHEET Reactions Of Unsaturated Hydrocarbons LAB A. These are known as hydrocarbons.
