Free radical halogenation is used to replace one or more hydrogens on an alkane with one or more halogens (either chlorine or bromine). It is a substitution reaction. A student performs a free radical bromination on 3-methyl-pentane (5.88 g) to create the desired product of 3-bromo-3-methyl-pentane. The product mix, which hopefully contains almost all 3-bromo-3-methyl-pentane, is cleaned up by passing it through a gas chromoatograph, which separates out the 3-bromo-3-methyl-pentane from any undesired products made during the reaction (undesired products are created frequently in free radical halogenation). The initial product mix weighed 9.45 g; the purified 3-bromo-3-methyl-pentane weighed 7.21 g. What is the student's percent recovery?

A saturated hydrocarbon burns in oxygen to give carbon dioxide and water. Approximately twice as much CO2 as H2O (by weight) is produced by this combustion, the actual factor being 2.03. Light induced chlorination of the hydrocarbon by 2.0 equivalents of chlorine gives a mixture of mono-, di- and trichloro compounds, along with small amounts of higher chlorination products. Only one monochloro isomer is formed, but there are two dichloro isomers and three trichloro isomers produced in the reaction. Based on this information, you should be able to identify the hydrocarbon, and draw structural formulas for the chlorinated compounds.
