II. Experimental Procedure : In a flask‚ 0.081 mol of 2-methycyclohexanol and 3 mL of 85% H3PO4 were mixed. The mixture was boiled under a fractional distillation column‚ and 7 mL of the distillate was collected. The organic and aqueous layers were separated and the organic layer was dried with anhydrous sodium sulfate. The product was analyzed using GC. III. Conclusion: In this experiment‚ 2-methylcyclohexanol was mixed with phosphoric acid with heat‚ to produce 3 isomers in one solution

human population to recycle (EPA‚ 2012). Compost itself is not hard to make and can produce many different types of microorganisms; especially bacteria (Diaper‚ 1994). The microorganisms will begin to eat away at the living organic matter until it completely dies then new organic matter must be added in order to keep the cycle going‚ and the microorganisms alive. As the cycle continues the population also continues to grow and the organisms in the compost will begin to become more complex. Since the

signifies the temperature at which the first crystal starts to melt until the temperature at which the last crystal disappears is reached. That being said‚ melting points are expressed in ranges‚ am organic compound will have a sharp range depending on the purity of the compound. Impurity of an organic substance will register an abnormal melting point based on its expected propensity observed‚ this will cause the temperature range to widen. Using this hypothesis‚ mixed melting point technique could

Analytical techniques for providing information about the total mineral content are based on the fact

process didn’t help to separate any layers‚ just made the product look turbid. Due to this I added a couple drops of water that helped the product to separate its layers. Conclusion: SN2 reactions are substitution reactions that are performed in organic labs. In this experiment 1-butanol was converted into 1-bromobutane by an SN2 reaction. The ending result of the experiment was to test if the product was correct by using a flame test that colorizes the product. The flame test turned green which
