Post Lab Report for 2-ethyl-1,3-hexandiol
Calculations
Theoretical yield: 1.857g
Product Yield: 1.055g ----> Percent yield = (1.055g/1.87g) x 100% = 56.41%
Starting amount of diol: 1.184g ----> Percent Yield = (1.184g/1.87g) x 100% = 63.32%

Structure
The Structure in my compound is: C8H18O2 + 2 ClO- → C8H14O2 + 2 Cl- + 2 H2O producing 2-ethyl-3-keto-1-hexanal.
The purpose of this experiment was to determine which of the 3 compounds was formed from the starting material. The third compound was the oxidation of both alcohols. This could not have been my product because of the results of my IR. I had a broad large absorption is the range of 3200 to 3500 wavenumbers. This indicates the presence of an alcohol. If my compound had been fully oxidized then there would be no such alcohol present. Also, because of my IR, I know that my compound was one of the other 2 compounds because of the strong sharp absorption at 1705 wavenumbers. This indicates the presence of a carbonyl. Therefore I had to prove which of the two compounds my final product was. The first was the oxidation of the primary alcohol, forming an aldehyde and a secondary alcohol. The textbook states that aldehydes show 2 characteristic absorption’s in the range of 2720-2820 wavenumbers. No such absorption’s were present in my sample. Therefore my final product was the oxidation of the secondary alcohol. My final product had a primary alcohol and a secondary ketone.
In this experiment, the secondary alcohol is selected over the primary alcohol. In many cases the primary alcohol can be oxidized all the way to a carboxylic acid. In order to achieve selectivity, sodium hypochlorite is used. It is reacted with acetic acid to form HOCl.

A distillation experiment was performed in attempt to separate two miscible fluids.This experiment used fractional distillation to separate ethanol from the azeotropic mixture of ethanol and water. The initial composition of the solution did not matter because the goal of the experiment was to distill the ethanol-water solution and obtain 95% ethanol in the distilled fraction. The percentage composition is obtained by the calculated density of distilled product. The azeotropicmixture was separated using a fractional distillation apparatus. The apparatus contained a fractional distillation column with acopper sponge; this was used to capture the water vapor to repeat the simple distillation process, this method yield 88% of ethanol. This form of distillation was shown to be effective in distilling a mixture with similar boiling points.…

In gymnosperms, pollination is the transfer of pollen (Fig. 2) from male cones (where pollen is produced) to female cones, which house eggs. In these plants, pollen is carried from male cones to female cones by wind - gymnosperms were the first plants to evolve that did not need free water to transfer sperm to egg, and were therefore able to thrive in terrestrial habitats. Pollen grains are also protected by tough coats. After fertilization, seeds are produced with developing embryos…
