Cyclohexene

The results collected illustrate that cyclohexene is the unknown. Comparing the measured boiling point of cyclohexene to the literature value of cyclohexane, there is only a difference of 0.3°C. Comparing the measured density of cyclohexene to the literature value of cyclohexane, there is only a difference of 0.027 g/mL difference and comparing measured refractive index of cyclohexene to the literature value of cyclohexane, there is only a .009 difference. All of these results shows that both the literature value and the experimented values show a very small difference therefore, the results are very well accurate.

However, cyclohexene consists a double bond which causes a slight difference between the values of the physical properties. As a result of the double bond in cyclohexene, the b.p., density, and refractive index of cyclohexene is slightly higher than cyclohexane. This double bond make cyclohexene harder to break apart, thus consisting the higher values of the physical properties.

At pH of 1, it is highly acidic and more H+ will be attracted on to the –NH2 group to form NH3+ therefore it is soluble in water. The conjugate base for cyclohexyl amine is the most unstable out of all the choices so it is very basic and the more basic the easier to dissolve in an acid. Cyclohexane carboxylic acid is most acidic of all. The conjugate base of cyclohexane carboxylic acid is very stable compared to the other cyclohexane derivatives, therefore it is very soluble in basic
