which the impurities are moved to the second solvent‚ leaving the sought after compound in the first solvent. The aqueous‚ carboxylic acid‚ solvent used is polar and the organic‚ ether‚ solvent is non-polar. The more dense solvent is the bottom layer. In this case the aqueous water is on the bottom layer and the ether is on the top. Density is one way to differentiate each layer but the identities still have to be confirmed. A general rule of solubility is like dissolves like. Non-polar compounds

Organic Chemistry II Lab Diels Alder Reaction Purpose: In this experiment a Diels-Alder reaction was used to form the products. Cyclopentadiene and maleic anhydride were reacted together to form cis-Norbornene-5‚6-endo-dicarboxylic anhydride. 7-oxabicyclo{2.2.1}hept-5-ene-2‚3-dicarboxylic anhydride was also produced through a Diels-Alder reaction with the combination of furan and maleic anhydride.

Phenylmagnesium bromide was then transformed into a tertiary alcohol called triphenylmethanol‚ through addition of another compound called benzophenone‚ as well as additional ether. The end product of triphenylmethanol was analyzed via NMR and IR. Figure 1: Preparation of the Grignard agent by combining bromobenzene with magnesium and ether to produce phenylmagnesium bromide.

simplest tertiary alcohol. It is one of the four isomers of butanol. Tert-Butanol is a clear liquid (or a colorless solid‚ depending on the ambient temperature) with a camphor-like odor. It is very soluble in water and miscible with ethanol and diethyl ether. It is unique among the isomers of butanol because it tends to be a solid at room temperature.

Our results displayed 5.70% 2‚4-dinitrotoluene and 1.53% 2‚6-dinitrotoluene. The compound is mixed with diethyl ether to isolate the organic products. This resulted in a light yellow mixture. It was then washed twice with 5% Na2CO3 because it is an ionic solution (more ionic than water) and will bond to the H+ ions. This resulted in a bright yellow mixture
