Analysis:
A1 vs. E1: Solubility with water (H2O) This test consists of two hydrocarbons, a cyclohexane and a cyclohexene, being added to water to test their solubility. Both the cyclohexane and cyclohexene reacted the same way after the water water was applied. Each chemical stayed afloat of the water although the physical/qualitative properties remained unchanged. The insoluble nature of the results in this test can be explained through the “like dissolves like” notion, where only polar molecules will dissolve polar molecules and vice versa (University of Oregon, 2012). Thus, the nonpolar molecules, cyclohexanes and cyclohexene, will not be soluble in the polar water molecules (University of Oregon, 2012).

A2 vs. E2: Reaction with concentrated sulfuric acid (H2SO4) …show more content…
There was no reaction between the acid and the cyclohexane.There was a slight colour change (yellow hue) that appeared at the bottom of the test tube- the cyclohexane and the acid did not mix. As for the cyclohexene, the product consisted of a dark brown mixture with a high viscosity. It was deemed soluble as the mixture also produced heat- an exothermic reaction. The results between the cyclohexene and the sulfuric acid were possible due to the attraction forces between a positive hydrogen ion (in solution) and a negative oxygen ion in the sulfuric acid- a carbon from the double bond (alkene) attaches to the oxygen atom (sulfuric acid). This type of interaction is called an electrophilic addition reaction (Clark, 2017). Therefore, cyclohexyl hydrogen sulfate otherwise known as cyclohexane hydrogen sulfate is
