The purpose of this lab is to understand the properties and reactions of hydrocarbons. This experiment has two procedures. The first procedure is to test the solubility of alkanes and the second is to test the solubility of alkanes when bromine is added to each solution. The results from the first test was that most of the alkanes were soluble, the ones that were not soluble did not change even if heat was added to try to promote solubility. The results from the second test when bromine was added was that there was no change to any of the solutions. The solubility of alkane’s results were accepted. While the results for the test when bromine was added were not accepted because there was no reaction from any of the solutions. Introduction
The universal rule for solubility is that “like dissolves like”. This means that polar alkanes will only dissolve in polar solutions while nonpolar alkanes with dissolve in nonpolar solutions. Alkanes are considered to by hydrocarbons that contain singe bonds between carbons. When testing for the solubility of a hydrocarbon either a homogeneous solution or heterogeneous solution will be seen. A homogeneous solution is one that does not have any layers which means the hydrocarbon is soluble, while a heterogeneous solution will form layers showing that the hydrocarbon is not soluble (Spurlock). See if what she says about the reactivity. Halogenation is defined as the replacement of one or more hydrogen atom within an organic compound by a halogen. In this experiment bromine is used as the halogen. Halogenation is a substitution reaction. Bromination is considered to be the most stable radical...
