Even aromatic compounds also react with conc. LAB #1 Reactions of Hydrocarbons Return. | Aromatic hydrocarbons are unreactive with bromine without a catalyst and resulted in the dilution of the color of bromine to orange to yellow. Jump to Page . Use the droppers where available, and, Glassware that is broken must be placed in the broken glass receptacle at the back of the, Any chemicals that remain in the test tubes must be disposed of in the proper waste. Alkanes are referred to as, and are relatively unreactive. As it undergoes a substitution reaction. Adding hexane had no visible change. … [pic 12][pic 13][pic 14][pic 15]. Hydrocarbons can be known and be differentiated by their physical properties and chemical reactivity. Best Answer. Alkenes possess at least one double-bonded carbon, in the chemical structure, and alkynes possess at least one triple-bonded carbon. You are on page 1 of 11. Experiment 1 -Period 3. Acetylene reacts with ammoniacal solution of forming acetylide of silver. EXPERIMENT #3 - REACTIONS OF HYDROCARBONS OBJECTIVES To understand the variations in reactivity of different types of hydrocarbons To perform chemical tests on alkanes, alkenes, alkynes. Alkenes are readily reactive to bromine since its double bonds can be broken easily though addition reaction also is relatively similar if alkenes are added to potassium permanganate. Under more vigorous conditions the geminal diol (from an alkene) that is initially produced will be further oxidized by the permanganate, producing more manganese dioxide. These hydrocarbons also react with concentrated . This preview shows page 1 - 3 out of 8 pages. To test the flammability, sulfonation, nitration, and bromination of aromatic, Aliphatic hydrocarbons can be classified as alkanes, alkenes, or alkynes. Unwrapped test tube with toluene reacted with Br because it is light initiated. Flammability of Aliphatic and Aromatic Hydrocarbons. To perform chemical tests on alkanes, alkenes, alkynes. Alkanes are unreactive to bromine unless under special condition or catalyst like being exposed to UV light also alkanes are unreactive to potassium permanganate. Solution although insoluble forming hydrogen bonds to the hydrocarbons. Baeyer Test Original color of potassium permanganate was a purple. If a hydrocarbon contains only single bonds, it is an alkane. Protective eyewear, lab coats, and closed-toe shoes must be worn at all times. Section Team Instructor REPORT SHEET LAB Reactions of Unsaturated22 Hydrocarbons A. Oxidation: Reaction with Baeyer’s Reagent, Dilute aqueous potassium permanganate oxidizes alkenes (cyclohexene) to geminal diols. Answers for Predicting Products of Chemical Reactions For all combustion reactions of hydrocarbons or hydrogen-carbon-oxygen molecules, the products will always be CO2 and H2O (assuming a complete reaction). View desktop site, Section Team Instructor REPORT SHEET LAB Reactions of Unsaturated22 Hydrocarbons A. As it undergoes a substitution reaction. Aromatic compounds are unreactive because they are usually stable and can only be reacted if given a catalyst. Types of Unsaturated Hydrocarbons Models of Unsaturated Hydrocarbons Compound Condensed Structural Compound Ethene Condensed Structural Formula cis-2-butene Propene Ethyne (acetylene) Cyclobutene Questions and Problems Q1 Write the IUPAC names of the following compounds: a. CHy-CH-CH2 b. CH-CH CH-CHs CH3 c. HC- C-CH2-CH2-CH d. 257. Same as when was added to cyclohexene. CHM1024 Report 4 : Reactions of Alcohols . Do not touch chemicals with your bare hands. Even aromatic compounds also react with conc. Alkenes and, , and are more reactive than their alkane, hydrocarbons contain one or more 6-carbon benzenoid structures. Alkyl groups are usually fairly resistant to oxidation. Universidad Tecnica de Manabi • INDUSTRIAL SEGURIDAD, Week #5 and 6-CH121 Exp#3 Reactions of Hydrocarbons.pdf, Copyright © 2020. Experiment 11. Acetylene formed when water reacts with calcium carbide. Privacy Types of Unsaturated Hydrocarbons Models of Unsaturated Hydrocarbons Compound Condensed Structural Compound Ethene Condensed Structural Formula cis-2-butene Propene Ethyne (acetylene) Cyclobutene Questions and Problems Q1 Write the IUPAC names of the following compounds: a. According to their solubility, these hydrocarbons are insoluble; immiscible to water as they are nonpolar substances as opposed to the high polarity of water. The densities are the same for each with the exception chlorobenzene due to the hydrogen bonds that have to be broken, the dispersion forces that are acting upon the molecule as opposed to making new bonds in reacting water with chlorobenzene. Formal Report, Carboxylic Acid and Derivatives. To test the flammability, sulfonation, nitration, and bromination of aromatic hydrocarbons. Tetrachloromethane (carbon tetrachloride) or cyclohexane are usually used as solvents because they are unreactive toward both … Hydrocarbons can be classified further by the type of bonds they contain.
