agent to ensure that pure cyclohexene was obtained‚ calcium chloride works by binding itself to the water molecule thus removing it in the process. After the dehydrating process was completed‚ a few tests using Potassium Permanganate solution and Bromine which were purple and Reddish-Orange respectively was conducted. The tests showed a positive result which indicated that the product was indeed pure cyclohexene. As a result of this‚ it was concluded that the activity was indeed a success as cyclohexene

place during this reaction. Introduction: One of the common ways of preparing an alkene is through the dehydration of an alcohol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene while using sulfuric acid as a catalyst. A bromine test can be later done to ensure that the end product is an alkene. Procedure: The procedure given on pages 24-25 in the CH102 Lab Manual 2012 was followed with a few modifications as follows. Steps 6 and 7 were interchanged‚ that is‚ first 10cm³

color‚ and odor were noted through simple observation. Miscibility of the test compounds were noted through color change or a warming effect. Flammability was tested by igniting 3-5 drops of the sample in a small evaporating dish. Baeyer’s test and Bromine test were used for tests for active unsaturation. Aromaticity of the compound was determined through nitration. Oxidation was tested by introducing 8 drops of 2% KMnO4 solution and 3 drops of 10% NaOH solution to 4 drops of the sample organic compound

The purpose of the lab “All in the Family” was to compare the reactivity of the halogens Chlorine‚ Bromine‚ and iodine by observing the reactions between their elemental forms and their ionic forms. To accomplish this experiment‚ we first added a squirt of pet ether to two test tubes. Then‚ we added the same amount of Cl2 to both of the tubes‚ shook the mixtures‚ and recorded the color that resided in each mixture as the initial color. After‚ a squirt of NaBr was added to one test tube‚ and a squirt

bromination with hydrogen peroxide and hydrobromic acid‚ and debromination with zinc. The yields of parts A‚ B‚ and C are as follows: 68.6 %‚ 54.6 %‚ and 55.9 %. Introduction In the chemical process of bromination‚ an alkene is halogenated with bromine. Solvents that are typically used include methylene chloride and carbon tetrachloride along with iodine‚ the traditional reagent. However‚ because of the carcinogenic properties of the solvents and the corrosiveness of iodine‚ other alternatives are

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)

is finally tested to determine whether or not it has been dehydrated. The three tests used were infrared spectroscopy‚ Bromine chemical test and Bayer’s chemical test. The infrared spectroscopy showed a large narrow peak at 3062.12(cm-1) and 3020.71(cm-1) which indicates that there is a double bond present. To assure the results were correct the chemical tests were done. The Bromine test was found to be positive for cyclohexene. The OH group was removed from the cyclohexanol and replaced with a double
