Cyclohexene: Completely Decolorized Discussion: 1) Assuming the reactions of these hydrocarbons are typical of the classes of compounds which they belong what can you say about the relative relativities of the three classes? The Alkenes are the most reactive type of hydrocarbon as in both reactions ‚ they decolorized when bromine water was added‚ of which is usually brown‚ and when potassium

hydrocarbon and cyclohexene is an unsaturated hydrocarbon due to the presence of double bond.Both hydrocarbons produce carbon dioxide and water during combustion test. When the oxygen is limited‚ the product will be carbon monoxide and water. The alkenes are highly flammable and burn readily in air‚ forming carbon dioxide and water. In this experiment‚ the combustion of cyclohexene burns in an orange flame and produces relatively high amount of black soot. The black soot produced is actually carbon

Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because

fractions from the refining of petroleum Catalytic cracking is the process whereby high molecular weight fractions are broken down to low molecular weight ones. This process is used in petroleum refineries where crude oil is broken down to smaller alkenes and alkanes‚ until ethene‚ propene‚ (or both) are formed. Catalytic Cracking allows greater output of high-demand products. Identify that ethylene‚ because of the high reactivity of its double bond‚ is readily transformed into many useful products

Chemistry Essay Butane‚ Butene and all isomers that come with them are considered to be alkanes and alkenes respectively. They differ from each other in the fact that Butane contains only single bonds‚ whereas Butene has both single and one double bond. Regardless of this difference in many situations the two molecules can display similar behaviours. For the purposes of this comparison But-1-ene will be used as ‘Butene’ unless otherwise indicated. But-1-ene is almost identical to the other

One major observation made throughout this experiment was during the steam distillation. As the steam distillation started and the solution in the flask began heating‚ it was clear that too much stopcock grease was used around the glassware. The grease from the connecting ends of the three way connecting tube was melting and seeping into the clove and water solution in the two necked round bottom flask. The solution in the flask was immediately discarded and repeated with clean glassware and a very

Preparation of Bromotriphenylmethane Abstract The structure of a major component of star anise oil was derived by analyzing its IR spectroscopy melting point of after oxidation and purification. From the evidence obtained‚ it was concluded that the exact structured should be p-methoxybenzoic acid. Introduction The purpose of this experiment is to determine the structure of the major component of star anise oil. It is already known that this component has a molecular formula C10H12O. This

Stereochemistry of Dihydroxylation Reactions Question: Can the stereochemical outcome of dihydroxylation reactions be determined by thin layer chromatography? Overview: In this experiment‚ you will perform two reactions that transform alkenes into diols. While similar in functional group transformation‚ these reactions may lead to stereochemically different products. The two possible products are diastereomers of one another‚ and therefore have different physical chracteristics. After
