    The objective of this experiment is to conduct a free radical reaction and measure the ratio of products through a GC analysis. Free radical reactions are important to understand because they allow chemists to design synthesis of complex molecules from very simple organic molecules. The reagents used were 2‚3-dimethylbutane as the carbon chain‚ t-butyl peroxybenzoate as the initiator‚ and sulfuryl chloride as the source of chloride radicals. The predicted products are 1-chloro-2‚3-dimethylbutane

    in order to maintain the necessary internal environmental conditions to survive. These toxic molecules are known as free radicals that contain an unpaired electron on the outer orbit (Proljsak et al.2013). Some examples of free radicals that can be found in the cell are superoxide (O2-)‚ hydrogen peroxide (H2O2) and even reactive metals like copper and iron. These free radicals are produced based on the environment the individuals are exposed to. For instance the energy generated when cells discompose

    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

    In 1956‚ Denham Harman articulated the free radical theory of aging which states that ‘oxygen free radicals that are formed endogenously in live cells result in a pattern of cumulative damage’(9). The theory is also implied that the target of those radicals in the cellular system is random. In live cells‚ DNA‚ protein and lipid are targets for the free radical’s invasion. Damaging any of those vital macromolecules in live cell affects the physiology of the cell and may lead to apoptosis and cell
