Yılgör Experiment date:06.12.2010 Report Date: 20.12.2010 ABSTRACT In this experiment‚ the purpose was to investigate E1 elimination mechanism with the reaction of cyclohexanol to cyclohexene. The reaction was acid catalyzed dehydration of alcohol and with catalyst sulfuric acid cyclohexene was obtained from cyclohexanol. And the product was obtained from the simple distillation and later it was reacted with bromine and potassium permanganate. The observations and results were all recorded

are immiscible and all are flammable. Tests for active unsaturation indicate that hexane‚ heptane‚ cyclohexane‚ benzene and toluene are saturated while cyclohexene is actively unsaturated. Hexane‚ heptane‚ benzene‚ and toluene are classified as aliphatic while cyclohexane‚ and cyclohexene are aromatic. All are not oxidized except for cyclohexene. I. Introduction Hydrocarbons are compounds that contain only carbon and hydrogen. Hydrocarbons can be aromatic or aliphatic

Lab 22: 4-Methylcyclohexene Abstract: We treated 4-methylcyclohexanol with phosphoric acid‚ and after purification we produced the end product 4-methylcyclohexene. We determined we had a pure product based on the results of the tests with Br2 and KMnO4‚ as well as the IR absorbtion spectrum of the final product. Purpose: The purpose of this experiment is to obtain pure 4-methylcyclohexene by reacting 4-methylcyclohexanol and phosphoric acid. Through distillation

Department of Psychology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Four organic samples: hexane‚ cyclohexene‚ napthalene and toulene were given to serve as reference standards to characterize and distinguish four unknown given samples. Nitration‚ bromine and basic oxidation testswere conducted to classify the different samples from being an aliphatic‚ or aromatic

Analysis of Hydrocarbons Myra Gurango‚ Geneva Guy‚ Micah Hernandez* and Joyce Lagarde Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract The organic compounds hexane‚ toluene‚ cyclohexene and naphthalene in hexene were subjected to parallel chemical testing to differentiate their intrinsic physical properties in terms of structure and behavior. The physical state and color were noted by simple physical observation. Nitration Testing was conducted for preliminary

Three rings are present as well‚ two cyclohexene rings and one benzene ring. Attached to the first cyclohexene ring is one methyl group. On the second cyclohexene ring‚ two methyl groups are present as well as the ether group. On the benzene ring‚ the hydroxyl group is the substituent‚ and a pentane chain is attached to the ring as well. THC contains
