#3 Mark A. Bruder 07. T.A. Michael Hall Alkanes: Chlorination Introduction: The purpose of this experiment is to determine the reactivity of hydrogen atoms on a carbon chain using free radical chlorination. In this experiment 1-chlorobutane will be chlorinated with the combination of sulfuryl chloride and ABCN as an initiator to produce the chlorine radicals. The combination of 1-chlorobutane and sulfur chloride will produce four dichlorobutane

Chem 310-003 February 9th‚ 2013 Conclusion: Free Radical Chlorination The primary purpose of this experiment was to carry out the chlorination of 1-chlorobutane so that dichlorobutane formation was favored. Gas Chromatography was used to analyze the amount of dichlorobutane isomer produced in the free radical reaction. A mixture of 8mg of catalyst‚ 1mL of 1-chlorobutane‚ and 0.32mL of sulfuryl chloride was added to a microscale reflux apparatus. After 17mins the reaction

CHE 213-451 11-1-11 Title: Radical Chlorination of 1-Chlorobutane Abstract: The purpose of the lab is to form 4 different dichlorobutanes by reacting chlorine radicals with 1-chlorobutane. This is then analyzed by gas chromatography to determine the experimental abundance of each isomer. Results: 1‚1-dichlorobutane had an experimental abundance of 5.9%‚ 1‚2-dichlorobutane had an experimental abundance of 21.1%‚ 1‚3-dichlorobutane had an experimental abundance of 48.7%‚ 1‚4-dichlorobutane

Exercise 5 Comparing the Reaction Rates of Alkanes and Alkenes Group # 4 Members: Pangan‚ Sam Margarette Perales‚ Angelica Ibay‚ Sophia Irigan‚ Sharien May Sorensen‚ John Antonio Ocan‚ Emmanuel Submitted to: Ms. Ginalyn Cuenca Mr. Neil Abreo Date: December 6‚ 2012 Introduction Alkanes are hydrocarbons with only single bonds between the atoms. Saturated hydrocarbon is the other term for it. They are used as fuels because they are non-reactive and also do not conduct electricity

Alkanes This is the correct chemical term for compounds known as paraffins. They are considered the simplest organic compounds and are a family of chain hydrocarbons having the general formula C2H2n+2. All of the bonds are single bonds (-C-H-‚ and -C-C-). The chains can be straight or branched. The smaller members (less than 4 carbons) are gases‚ while larger ones (five to seventeen carbons) are liquids. Beyond seventeen carbons the alkanes are waxy solids. Structure: The simplest saturated acyclic

Hydrocarbons – Methane (Alkanes) Introduction to Hydrocarbons – Methane Carbons have the ability to form many different compounds. Compounds of carbon that only contain carbon and hydrogen are known as hydrocarbons. Most hydrocarbons naturally occur in the mixture crude oil. There are three main types of hydrocarbons‚ alkanes – saturated hydrocarbons made up of only single bonds‚ alkenes – unsaturated hydrocarbons with one or more double bond/s‚ and alkynes – unsaturated hydrocarbons with one or

Alkanes are saturated hydrocarbons. They contain only carbon-carbon and carbon-hydrogen single bonds. They are the least reactive of the organic compounds. The main source is crude oil. Hydrocarbon- a compound consisting only of hydrogen and carbon Saturated- Contain single carbon -carbon bonds only Unsaturated-contains a C=C bond Petroleum fraction- mixture of hydrocarbons with a similar chain length and boiling range The general formula for is CnH2n+2 (for ring alkanes is CnH2n)

Alkanes The reaction between alkanes and fluorine This reaction is explosive even in the cold and dark‚ and you tend to get carbon and hydrogen fluoride produced. It is of no particular interest. For example: The reaction between alkanes and iodine Iodine doesn’t react with the alkanes to any extent - at least‚ under normal lab conditions. The reactions between alkanes and chlorine or bromine There is no reaction in the dark. In the presence of a flame‚ the reactions are
