The purpose of this experiment, Free Radical Chlorination of 1-Chlorobutane, is to examine the influence of the molecular structure on the reactivity of an alkane in a free-radical chlorination using the technique of gas chromatography. In this experiment, 1-chlorobutane was used to react with sulfuryl chloride in order to produce four isometric dichlorobutanes. The percent compositions of the four isometric dichlorobutanes are 8.34% for 1,1 dichlorobutane, 21.30% for 1,2 dichlorobutane, 44.50% for 1,3 dichlorobutane, and 25.86% for 1,4 dichlorobutane. The Relative Reactivities per hydrogen of the C-1, C-2, and C-3 positions in 1-chlorobutane compared to the C-4 position was 0.48: 1.24: 2.58: 1. These results show us that the primary hydrogens
