ethanol and 2-propanol were both 0%. The percent recovery of the intermediate was 96%. The percent efficiency calculated of ethanol and 2-propanol was 0% efficient. Next‚ Cyclohexane and Toluene were distilled. The boiling points of cyclohexane and toluene had a difference of 35°C. Cyclohexane had a percent recovery of 10%. Toluene had a percent recovery of 17%.

f Fractional Distillation of a Solution Results 1. On a single graph‚ plot boiling point versus volume of distillate curves for the two distillations of the cyclohexane/toluene solutions (one from the simple distillation experiment and one from the fractional distillation experiment). The graph is to be computer generated and presentation quality (e.g.‚ appropriately scaled and labeled axes‚ descriptive title‚ and discernable data points). The data points are to be connected with a smooth

For cyclohexane I mixed it with fraction A‚ since it predominantly consisted of my low boiling point liquid‚ and observed two peaks in my results. Therefore I concluded that cyclohexane was the low boiling point liquid. However‚ for the second liquid I guessed heptane first‚ and my results showed three peaks. Knowing that I had guessed wrong‚ I tested toluene mixed with my fraction C and only got two peaks. The high boiling point

Analysis of Hydrocarbons Jennifer Alambra‚ Ma. Nancy Anulat‚ Alfonso Apepe*‚ Jacqueline Arsenal 3Bio4 Department of Biological Sciences - College of Science‚ University of Santo Tomas‚ Manila ABSTRACT The unknown hydrocarbon sample was differentiated and characterized by the use of three tests. The outcomes of these tests are as follows: Nitration test (negative)‚ Bromine test (positive) and Basic Oxidation test (positive). From these results the unknown sample can be classified

Name of the Experiment: Simple Distillation (Semimicroscale Procedure.) Abstract: Distillation is a method of process of separating 1:1 mixture based on differences in their volatilities in a boiling liquid mixture. Distillation is done with the use of simple distillation apparatus shown in Figure 1. In this experiment‚ simple distillation process was used to determine the identities of the unknown compounds in the solution through the obtained boiling points. The list of probable unknown volatile

Tests for active unsaturation indicate that hexane‚ heptane‚ cyclohexane‚ benzene and toluene are saturated while cyclohexene is actively unsaturated. Hexane‚ heptane‚ benzene‚ and toluene are classified as aliphatic while cyclohexane‚ and cyclohexene are aromatic. All are not oxidized except for cyclohexene. I.

chloride with their respective hydrocarbon (10 drops) as well as the addition of a small amount of bromine. One group of tubes was set in the light and one was set in the dark and when compared‚ you were already able to see that the ethylbenzene and toluene were the fastest to react in both situations. Due to this fact we can tell since they were the fastest reacting‚ they can be associated with the fact that they were more than likely secondary and primary benzylic carbons due to their excellent stability

radical is more selective. Since bromine is more selective‚ it is used in most experiments. Conclusion The predicted reactivity of the five hydrocarbons in free-radical chain bromination in increasing order was ethylbenzene (9)‚ toluene (8)‚ methylcyclohexane (13)‚ cyclohexane (12)‚ and tert-butylbenzene (11). This hypothesis was a result of the fact that benzylic hydrogen atoms react faster than aliphatic hydrogen atoms and aliphatic hydrogen atoms react faster than aromatic hydrogen atom atoms. The
